I was thinking the same thing. Hmmm gee..... That kit might weight almost 100lbs but doubles my hp... Decisions decisions

Well, looks like I'm going home sooner than I thought. Contracting changes, the drawdown in AFG, and some misleading (outright incorrect) information, I will be heading home by the end of the month. This means I need my car sooner than I had hoped. So I messaged GTM about the change so we both know what we are working with.

Mike said the car is throwing P0300 and P0172 codes. O2 sensor and fuel trims are all over the place and they strongly believe the O2 sensors were wired incorrectly. I distinctly remember thinking the same thing and asked the shop about it. They claimed they extended it one wire at a time. I also remember replacing an O2 sensor too. I told them everything I did last year as I was chasing this same thing. I'm happy my suspicions are true, but also upset that the issue is still present. This could very well explain the lower than normal power numbers compared to a similarly modified vehicle.

Edit: To elaborate my thoughts a bit more... Which I was suspicious of all along with the headers because I had a SES since they were installed. To think the car gained 30whp with an exhaust and headers and O2 sensors reading retarded is crazy, and gaining 46 with intakes and pulley's is surprising in retrospect with this issue being here as long as it has. I was anticipating over 50whp gains for those mod. My torque was always soft for the mods I had. Full stepped headers and an M370 should have helped immensely. I was also expecting torque to be around 260lbft and it was only 245, so power under the curve was soft. Looking at the latest dyno graphs, the line isn't as smooth as other peoples graphs (dynojet). Nearly all of my gains are at the top and that's probably because no restriction, but very little in the mid range where it should be strong.

Edit: I was able to prove that I was mislead with bad information from old management and got my time to get my CCNP cert pushed to the original June date I had. I have the switch test done which I came to find out was considered the hardest, and hitting route in a few days. It looks like I won't be going home early anymore

Man oh man, what a day!!! Let me start by some good news. I passed my TSHOOT exam for CCNP, I'll be completing my contract through August. Such a load off my shoulders as today was the deadline.That's the only good news I have though... well maybe some good news for guys looking for parts off my car when I get home.

So all of my fears have been realized with this build... I got an email from Mike and none of it was pleasant news except the fact that they know the fix action.

"As you know, your car has a CEL P0300 and had that code when it came in. We took a peek under there and noticed that the previous shop had put the primary sensor in the J tube instead of the freestream bung. We switched them around and there was no change. It looks like the previous shop extended the wrong O2 sensor wires. In addition, the wires appear to be crossed which melted and shorted the wiring. You will need two new O2 sensors as well since they were shorted out. Because the O2 sensor wires are shorted, there is a small chance that may have damaged the ECU so we need time to diagnose your car and check the ECU. I have attached some pictures of the wiring and O2 sensors so you can see what we're talking about. Overall, we need an additional 5 hours for diagnosis, repair, re-wiring, checking the ECU, and replacing the 2 O2 sensors plus the cost of two new sensors.

Next, the CSF radiator will not work since the water neck is a one piece setup whereas the stock radiator is a two piece setup. That means the water neck on the CSF radiator will interfere with the supercharger on the passenger side. We have a special elbow that replaces the stock elbow to give clearance between the water neck and the supercharger. Since the CSF is a one piece elbow, we can't use our elbow. Also, we use different radiator hoses to clear the supercharger brackets, belts and pulleys so your silicone radiator hoses won't work either.

Finally, your 72 row oil cooler is 2" wide and there is nowhere to mount it since there is not enough room to put it anywhere."

So yeah, if you go back and read through this journal, I've already questioned the oil cooler and O2 sensors. I was not expecting the CSF radiator to be an issue as well. I called them to discuss it a bit. I will be receiving a quote for the O2 sensors, the labor, their radiator/fan kit, and oil cooler kit... one that is equivalent to my 72 row. Here are the images they shared with me as well. It pains me








So the good news for some of you all... Parts will be available in a few months

AE Performance 72 row oil cooler
Brand new CSF radiator (spoken for)
NST pulleys (spoken for currently)
AEM Gunmetal CAI (spoken for already)
Red Z1 polyurethane hoses (spoken for)

PM me if you want details on these parts. I won't be home until late August, so it will be some time.

For the record... making 310whp STD is pretty impressive after seeing this botch. I wish I knew what it could have been if she was running right.

I hate reading about situations like this. Sorry for your troubles. Hopefully you get it sorted out. Are you selling the car, or just getting rid of some of the parts?

Just parts Have to get GTM stuff and spend more $$$ lol.. not really a laughing matter

Wow sorry to here about the set backs and botch job. Fingers crossed your ecu is ok. Blows about not being able to use your radiator. Did u go with the competition radiator with heat exchanger in it and HO spal fans like i did? Seems to be a kick *** setup but not inexpensive by any means, but nothing I have done on this build has been at this point. Our cars are garage mates awhile longer as mine is sitting waiting for aero parts from Japan. Needed to move around the 2 34r oil coolers so we can get more air flow to the radiator so I will be able to drive it here in AZ. Getting tired of waiting thou. Started this project a year ago.Hopefully they can get yours wrapped up and to you for when u get home.

Haha, twin 34's are pretty serious. Mine being SC, there isn't quite as much of a load on the cooling. I'm wondering what they recommend. But I will most likely get their competition radiator and SPAL fan setup. With the oil cooler, I think twin 25's would suffice. Hopefully there is enough air flow... I just feel like I wasted money on the radiator and red hoses. The oil cooler, I love that thing, I am not happy it won't fit. It was insanely expensive and worth every penny. I would be 115 outside and I'm stuck in a traffic jam, it might creep up to 220... The second I start moving, it steadily drops. Highway speeds in the same heat was around 200. While tuning, it stayed at 180, runs down the drag strip and idling in line, 180. It was a great oil cooler.

If I were you, I check if they even work with your kit in the first place

Edit: Just going to add an update to this post. I'll most likely get a recommendation and quote from GTM on Monday for everything. My initial guess so far is their 70mm radiator upgrade with built in heat exchanger, a 25 row oil cooler, shroud and SPAL fan kit. I was looking at their twin oil cooler setup as well, but that blocks more of the radiator and with the IC's up front, airflow will already be reduced. Just my thoughts.

So much for receiving a quote from GTM I was supposed to get on Monday... Same damn thing every week. Whatever timeline they give you, double it, it will be more accurate. Told them to fix the damn thing and add it to the tab. I still want to know how much it costs, and their recommendations for replacing the stuff that won't fit! I know it's going to add a few grand to the total cost... I do have other bills and it would be nice to figure out what the F@CK is going on! I may need to call them tomorrow. Luckily their work is superb, but their timelines are not. Month 7 btw. I'm sure they will use all 9 that they had available. Okay I'm done ranting.

Edit: 6/14/13
Sam emailed me yesterday saying he was going to send it later that day, still got nothing, all day today, still nothing. I sent another email 30 minutes after their stores hours were closed, will wait all day tomorrow, and will just call them on Saturday before work if I don't receive anything. All I want is an updated invoice on the new parts needed. This doesn't take two weeks to email to a customer. I understand they're busy with the MHI kit, instructions for both mine and the MHI, and all their other side projects, but that excuse only excuses so much. Two weeks is really just unacceptable. May 31st was when I was told my stuff won't fit and they will prep a quote by Monday. I emailed on the 6th about the quote, nothing, called on the 11th, or Monday morning, they said they would get it out to me that day (didn't catch name due to delay in line). Emailed at the end of the day because it did not come. Emailed on the 12th, Sam emailed back saying he will get it out today, did not receive that either. Emailed this morning, the 14th as a reminder, still nothing. Just sent my last email before I resort to calling and staying on the F'n phone till I get it in my inbox. I'm disappointed right now. It's the little things that are irritating. I'm spending a lot of money, I'm no special customer, or some baller customer or anything like that. It's not out of line for what people pay to have stuff done there. I limit inquiries to biweekly, with this quote issue being the exception (supposed to only be a couple days wait). If I give someone a date and time, I expect to deliver by that time. Give me an accurate estimate. They aren't even in the same ballpark.

My Dad just did some exterior changes to his Mustang. Vid is low res, but the bulbs look awesome, changed the tail lights. Shelby rims are sexy too! He just added slotted/drilled rotors as well.



Edit: 6/9/13 (compressing posts)

Wow, found this on the interwebs. My first run at the strip here in Vegas. It wasn't a very great time or trap, but I had fun. Car's O2's were wired all assed up back then too. This was with all my bolt on's



Here is my buddies Z. He has lowering springs, Berk HFC's, Berk CBE, AEM CAI, no tune at the time.

Created a sale thread for all my parts Parts 4 Sale GTM will ship straight to the customer for me Everyone who said they wanted something has been marked as such and reserved in the thread. If they decide to opt out, it will be up. If I don't receive payment in 7 days, it will be up for sale as well.

Talked to Sam@GTM extensively today. Finally gotten things ironed out. Pending Wife approval, I'll be getting their competition radiator, SPAL fan shroud, twin 25 row oil cooler, and new baffled oil pan. This is costing me a terrible amount of money and my parts sale really only covers half of what I have to pony up. Looking at the quote felt like I got gut punched. It is what it is. Everything he told me about why to get this amount of cooling was exactly what I already knew and needed to hear from a subject matter expert so I can justify the wallet pain. In retrospect, I would not have done this if I knew how much this is turning out to be. One leg is already in, so I'm finishing what I started. Lastly, I picked up a used set of Whiteline Swaybars those were a fraction of the cost of what that quote looked like lol.

Almost forgot... Sam also told me the Z1 brake kit is on and rewireing/replacing the O2 sensors fixed everything!!! He also told me they can have everything wrapped up in a month. It was about the only real good news I received lol.

Edit:Wive approves. Full steam ahead!

If people really knew the price of forced induction... HAHA! I smell a lot of upselling going on soon. Well played GTM. This has gone over budget by 60% already LOL. I'm just relieved everything is back on track and full steam ahead. I couldn't stop cursing at the PDF file that GTM sent.
