STS 370Z Single Turbo System

Chinook

Waste gate crack pressure it seems to spool earlier and quicker and I think sounds better unless it's in my head. Are you coming for the dyno days?

Did u get the electronic one from STs? And yes I am

I actually used my boost gauge, I have the aem tru boost gauge which also works as a controller as well. It was pretty easy to set up and seems to be working pretty well

I really hope the motocross spark plugs I pulled out last weekend don't come standard with these kits. Not only have I found that but now my Cat's might be fried. Lovin your system so far..... but somehow diffrent.

Didn't STS say that the stock cats would be fine? lol Well... I did warn everyone about it but STS assured that it wouldn't be an issue.

Uhhh what do you mean motocross plugs ? Lots of plugs are used for different things

tower74

I looked the part number up on the plug...it came up as motorcross dirt bike plug. Either the jagoffs that installed my kit did it or STS sent them with the kit. They run about $5.99 each.

I've also had this kit on for 9 months and 10,000+ miles...ohh yeah and without a proper tune that I had paid for to begin with.

I've waved the STS flag and tried to hold my tongue on all the issues I have had with the kit. Mainly because I had the first AT7. If I can find an UpRev tuner and get this tuned I might come back to there side. As of now I'm about a 1/2 second away from ripping out this system, which when changing the oil is a royal pain i the asz to get to the oil filter, and going back to a stock set up. Now with the 100+ heat I can drive my car about 15 miles before it tries to overheat. DONE!

This tune you paid for, is it the canned tune from sts or from a local tuner? Keep in mind most manufactures never recommend keeping canned tunes, you should always get tuned for the conditions you live in. If you have been running the canned tune from sts it would explain a lot of your issues.

Yea u need the custom tune from SEBZ !!!!

tower74

Nope bought the full tuner kit from them. Which includes tuning from STS. This has been ongoing issue since the first code was thrown back in Feb. First was a random misfire, which I thought was a bad plug but turned out it was the tune. In reality it was the motocross plugs.

Every tune that was done by STS was an e-mail tune.

Have you talked to steve and Rick? I didn't know all this was going on

tower74

I've dealing with Marc but I haven't talked to him for over a month. I had told him in an e-mail that when I bought this kit I talked directly to Rick Squires and he told me the kit was ready minus a few bugs to work out. Then they wanted me to drop another $3500 and send the car to them so they could map the car out and then get it their standards. Also it would make my car a templet for all other AT7 370's. Like I said early I realize they have yet to do a AT7 tranny and I would have a few issues.
This has been one issue after another and I been quit about it trying to get them fixed as they appeared with STS. After this last time I've had it with the kit.
Even when I had it at my tuners shop and he was working with Marc he was still unable to get the cars AFR above a 10. I'm still waiting on my tuner to get his UpRev license so I can have him do the tune. Which yet again was another $450 out my pocket which was part of the original purchase. So that's $650 plus at least another $1000 in lost work, fuel, etc out my pocket trying to get this thing to work but with no success.

Hell, I don't even know if the injectors were shipped with kit or if they were shipped if they were even installed. Plus, I would hope they would not send copper plugs for a turbo kit. I spent $200 on 6 new HKS Iridium plugs.

Chinook

Sebz from Specialty Z pulled the spark plugs in mine when he came up for a dyno tune and they were NGK iridium plugs. They were installed by STS when they installed my kit last summer so I doubt that they changed spark plugs after they installed on my car.

A one step colder plug is a one step colder plug across the board , doesn't matter what you use them in lol, and what makes you think your cats fried ?

tower74

I've have a check engine light. When I went to O'Reilys and use their ODII reader I got a P0430 code. Which is the Cat's. I knew it was only a matter of time with the tune STS sent that was keeping me in the 9's and they can't figure out why....

Trust me the car sat for almost 2 weeks when the intake solenoid valve went out...and the cam sensor....and then the pulgs....I think the next should be the engine. It's the only thing left.
