well I got up there with 10 other people about half stangs(93 saleen with paxton novi 1000, 04 gt, 02 gt, 99 gt,) So i go up there hoping to find out why I get waxed by pretty much every car out on the street even after my full exhaust and 3.73s. So first pull and i put down 180.2 hp and 213.1 tq. I was pissed to say the least but it was popping really bad through every gear and i started to get a lot of questions about what had been done to it(new maf, ignition, lines or pump) but I told them my only mods and they look at my air to fuel ratio and it was off the chart lean(about 20:1) so the chech my fuel pressure and its running 42 lbs so everything there is pre good and i do another run and put down 196.4hp and 228.1tq. Still not happy they and running now 19:1 ratio they unhooked a sensor that connects to the left side of the intake and we run it again and I put down 217.0hp and 253.9tq. I was a lil happier but still not where I want it(now running 17:1 a/f ratio) Well its running a lot better and I'm going back Thursday to run a diagnostic on it and were going to be changing out the fuel pressure regulator and check all the sensors to get my car running more rich. He told me I'm lucky I didn't burn a hole through my pistons. BTW I'm dead even with my buddy in his 1995 TA running consisten 13.8's and we mad 8-10 runs too so that made me quite happy saying i ran a 15.0 before

19:1 and they did a full pull?! I would have been pissed if it was me... They should be watching that when doing the dyno runs... To me that looks lean enough to do some damage...

Looks like your missing some torque too... You get your AFR fixed and it should help that out... Besides that 217 is doing pretty good for the mods you have...

From my understanding torque likes rich conditions..

lean conditions that high are scary. Dont do any hard driving on the car until you get that down in the lower teens for your A/F ratio. If that was a blown car you could say bye bye to your motor, good thing its N/A but even being N/A thats still in the danger zone of being to lean. DONT DRIVE IT HARD!!! you will regret it.
