I was recently installed the FAST 92 combo, 42lb injectors, underdrive pulley, 4" magnaflow, as well as a 150 shot on teh car so I decided to get it retuned and dynoed to see where she stands. The car made 375rwhp 350 rwtq last november cam only with ls6 intake and long tubes through the 10 bolt and a flowmaster. My deal on heads fell through and I was stuck with the stock 98 heads that are full of trash. First pull after getting it adjusted for the 42lb injectors and more air and it went 430rwhp and 391 rwtq through the 9". First pass on motor it went 12.4's spinning because the air guage was off and the slicks had almost 20lbs in them instead of under 15lbs. Next pass went 12.4's again but still couldn't get it to launch. Decided to hit it with the spray and first pass it went 7.21 in the 1/8th but didn't give me anything after that and I had to shift to 5th after taking it to 6,800-6,900 rpms in 4th. Next pass it went 7.27 in the 1/8th and 11.25 in the 1/4 but it ran out of gear and I had to let off because I didn't want to shift to 5th. Not too bad for a 138,000 mile car, I don't think.
