Any STS users out there?
I think red91z meant a 3200 converter.
What's screaming in your face right now is TUNING!!!!! The tune you have sucks if you are at 13.7. 13.7 isn't horribly lean, its flat out parts breaking, motor destroying lean on a boosted application.
So what if you've spent 1000 bucks on tunes, seems your tuner(s) suck ***** at tuning so why go back???? Find a decent place to tune your ride. Another member suggested you go to jeff creach...go to him whats it going to hurt...if anything your can't run any worse after his tune.
Safe street/strip tune on a boosted app should be 11.5 to 11.7-1 PERIOD.
Do a leakdown test on your engine, with that tune I wouldn't doubt there is damage to the pistons...especially if you are beating on it at the track. First start off by checking you plugs, prolly melted off a few electrodes...check for bits of aluminum on the plugs....if there is a lot...definately do a leak down or have on performed for you.
Some advice, don't beat on the car, take it to the track or dyno until you know the tune is in the ball park or optimized. If not you'll be posting that you tossed a piston and blame the STS kit. You can't just slap the kit on the car, get a tune that you know sucks and run decently.
On a stock car with an STS kit at 5-7 psi any LS1 should be in the 12s.
Nice post
Be happy that your tune has not lead to destroying your motor! Thats what happen to me and I would have gladly thrown away $11oo if I had the option instead of paying $600 for a tune and then another $4000 on repairs to the motor! And when I get it all fixed Guess what - I gota go have it Tuned AGAIN! Sounds like you have bin luckey so far. Fix the problems and then make a judgment on the kit. IMHO, Lata, Ark
PS. In response to a previous thread, my best 60' times is 2.3

I think a big problem is who you bought the kit from. Didn't they explain the extra's you need to make it run 100% safe/good? We alway's explain what should go with the kit. Also I find it hard to believe your out of pump with 42's and a stock engine with the STS.Ussually it will support 460rwhp on an auto.
The good part is the KR sensor's probly saved you a motor.
I got my car dyno'd and this is the graph, it looks very rough to me. Can you notice something wrong w/ it, is there anything wrong and if there is does that relate w/ my poor performance at the track?

I got the fuel pump comment since the AFR isnt going leaner at top, but correct me I am wrong, the fuel pump will quickly become an issues once it is tuned correctly?
What AFR do you shoot for on the STS, is it different than conventional turbo setups?
