112 mph should be good for low 12s, was traction a problem?

112 is enough for 11's if you 60ft the hell out of it :-)

If its on a stock tune now I wouldnt even drive it. You will kill it and wash down the walls/rings. (unless u can verify otherwise with a wideband or scanner)

Hit the DIY PROM board here. For less than what u would pay to get it tuned u can get the stuff yourself.

That things is so pig rich at idle and lower rpm's your eyes are prolly burning, and if u have cats on it still, there done too.

Bare min would be set the injector constant to 34, put the fuel pressure back to 43.5 line off. Prolly pull 15-20% of the fuel out at lower rpms below 1600 or so and start from there.

Mail order tunes are for the most part guesses and thats all. Read the stickies we assembled on the prom board. If your willing to pay gas and food and we can work something out I will try and help you if u start learning how to.

later

i have tuner pro rt but i am still trying to figure out how to record a data stream. I was thinking if icould capture the data stream i could sent it to ls racing and have him improve on what i have. my tune was only $170 and it is very streetable. I have a great starting point. just want to get the fueling and ign curves closer
