Tuning - No increase?
 

So i have the following mods: Stillen G2 intakes, FI res test pipes and invidia gemini CAT back exhaust. I went to get tuning done on recommendation from a friend and after about 7 hours worth of a wasted Saturday he was unable to make any power at all. He called Uprev and they told him "it's possible to not make power on these cars. It's pretty much hit and miss."

The car is running rich (i can smell it and the readings from the o2's confirmed that) which means i'm losing power to begin with just based on that alone yet he couldnt produce any gains?

My baseline with mods (no tuning) was 306whp. I'm expecting to be in the 320's with tuning or at least close to it. Am I losing my mind or shouldn't I be making some power after tuning???

P.S. now i need to go somewhere else to get tuning done an hope to make power without wasting my money.

So yout still made 306WHP? Not sure what you are saying. I made 1.5 WHP up top when I got tuned but made 18-22+in the mid range. What where you numbers before and after and what where your tuned A/F's?

You should see an increase in power after a tune with those mods...

Here's my chart

You should see more torque in the mid range but overall hp gains will be minimal from the automatic gains from the bolt ons. 306WHP is pertty good for what you have. The tune is only going to make the car more driveable with useable torques and removed rev limiters and WOT. Don't expect 20 hp out of the tune alone... these cars are very well tuned to begin with. Clean up your AFR's and you will be good to go. UpRev DOES make a huge difference but it will not throw extra buckets of HP at you! lol

I made 306 whp with my mods and no tuning (before) made the same after tuning so no increase.

Yeah right now i dont feel any difference at all and i have a pretty sensitive butt-dyno.

when he tried to get my air/fuels in range i actually lost power. When he added fuel to make it run rich I gained power. WTF? :icon14:

My air/fuels are around 11.5. It should be around 12.5 from my understanding which means there is room to make power in tuning.

OK so same as me, I made 296, Then 25 mins later tuned it the car and made 298. But all my gains where in the mid range. Maybe a tuner Error issue? Where did you go?

Definitely an issue with the quality of tuner.... buy a canned tune from Specialty Z and Sebz... :twocents:

I'd rather not say until i get it tuned somewhere else and see the results. If i go somewhere else and get results then I'll warn everyone lol.

Post your dyno sheet up. Might help us see where you need help...

If these were runs on a dynojet, see if you can get the actual datafiles from the shop (i.e., the drf's).

If you can, email them to me, and I can make detailed charts to see what's going on.

I think 306 is pretty awesome for your mods, you probably didnt need one to begin with. A dyno shop here in Houston told me you only need to tune if you change the diameter of the MAF tubes which most intakes do not.

I made zero HP but the drive-ability was much improved and the mid range was a bit fatter.

What was the dyno?

Does the G2 change the diameter of the pipe where the MAF is installed? That can throw off air/fuel readings but UpRev has a place to enter a correction for that.

The GEN II intakes are the same as the GEN III piping, just shorter.

Need to see the dyno!!

now u guys are really gonna kill me...no dyno sheets. I knew i was going to need to get it redone and after being so pissed i just left. I'll call him and see if i can get them.

I'll be the one to say it.

It really sounds like to me your tunner has no idea how to tune with Osiris. From the sound of it all he did was mess with the fuel table. There is more to a dyno tune then messing with the fuel table.
Do you have the ROM he tuned for you?

i just had an argument with him about getting the rom file since i paid for the license. He wont give it to me so i told him to take uprev off my car and give me my money back. Thats happening Wednesday so hopefully that will be the end of that. Then i can invest in a real tune.

Good Deal.. Glad to this this happen for you..

Any suggestion on where to go for tuning? I already talked to RAD since that seems like a good choice. Just hate to wait for the list lol

I bought my UpRev direct and got the 3 canned etunes plus the base tune. I am VERY happy with the results and I had a few people look at the map and they were impressed. Plus you get the data cable that way too!

RAD. Nuff said.:tup:

But if you insist on options R/T tuning down here in PA is a protuner if I recall correctly. Regardless there plenty if good reviews here on the forum about them.

My car is running 13.2-13.5 AFR after tuning, it didn't like anything under 13. Then again, I have my own gremlins I'm on a witchhunt for. I only made 306 after tuning, and that was with a laundry list of boltons.

If you're only looking at peak numbers, you are likely to be disappointed. Look at the area under the curve in the low to mid RPM ranges. If there are no gains ANYWHERE across the rev range, then something is up. If you gained 15-20 HP at low RPM but your peak number stayed the same, I would count that as a big improvement.

Also what were your torque gains in the low to mid RPM ranges? Remember, peak numbers are good for bench racing, gains in the low to mid RPM range is what makes the car faster and more fun to drive on the street.

You should name the shop
 

For the good of the members here, you should name the shop. You stated facts as you saw them, if the shop saw something else, they will tell their story.

I & others are looking for a tune shop. The right thing to do is tell us where you went & we will make our own decision.

When was your last contact with "theexperince.com"?
I've tried many times & can't reach them.

It's either me:) or they have some serious situation after their crew went to RAD....

With the mods you have you should see some peak gains with larger mid range gains. Sometimes the ecu's have adapted really well and gains are initially hard to see but after it is tuned and the targets are adjusted you should feel more responsiveness and more linear power as those targets are hit.

We will provide you with a before and after dyno sheet as well as you ROM file if you request it. We feel the ROM is yours as that is what we are being paid to provide you with. We are the most experienced UPREV tuner in the northeast...:tup::tup:

Give us a call if you are looking for another pro tune.

Where are you located?

Like I said once i take the car somewhere else and see the difference for myself then i will be 100% confident that the first person didnt know what they were doing. Until then I'm not giving out information.

To me that's the right thing to do and thats the way i'm going.

Post the shop Nick!!! LOL. I have a feeling I know who it is. And its funny you should have this problem because I'm waiting to get my car on RAD's dyno because me and about 10 other people think there is something wrong with my cars tune I.E Running really rich. And I'm curious to know if its the same shop and if it is the same shop there is another member on this forum that had to have his Z retuned by the same shop because the car started to run really rich again.

I've heard of a similar issue from several people in that area, I'd really like to see the rom file to see what that shop is doing...

You mean the shop with the really high reading dyno? :stirthepot:
If it is, then I think I've been there before, but luckily not to get any work done :p

Sorry to hear that nick

Its definitely not the same shop. This was in Westchester. You're numbers are extremely high! 339whp bolted? somethings up.

Numbers between dyno's aren't comparable. Different dyno types give different readings, Mustang and Dyno Dynamics read the lowest but are good for tuning because they are dynamic load dyno's. Dynojet's tend to read the highest but are inertia dyno's of fixed mass and don't give as much tuning flexibility. 280 on a Dyno Dynamics could be 330 on a Dynojet, so quoting WHP numbers without context on where they came from is pretty meaningless. Even a given dyno type can have fairly varied reading between different shops depending on how well it is calibrated.

Sooo how do u explain 339 on a mustang?

Different calibrations are possible. He could go do a different mustang dyno and get 300.

This is true

Once RAD has the dyno up and running I'm hoping to get more accurate numbers and fix my possible tuning issue.
