[QUOTE="kowalmustang, post: 15445083, member: 143826"] I had similar problems as you. NA my car would run 11.9 at 119 with a 1.8 60 with the whipple and the 3.375 pulley the car ran same 11.9 at 122.5. I had a whole tread about it here on svtperformance. What I did is gapped the spark plugs to .030 and added water weter to the intercooler reservoir. Also check your boost bypass valve it should bypass at idle so your IAT2 don't rise. Ever since then my car has went 11.7 at 125.5 on the same tire spinning the whole 2nd gear. I then put some old 19' drag radials on and the car did a 11.4 at 124. I was hot lapping the car and it must have pulled the timing on that run because the trap went down. Log your runs and make sure the IAT2 are below 130F. I made 524hp to the wheel and was getting 17.5 degrees of timing and .78 lambse. Your trap speed is definitely weak something is wrong. What I have noticed is that even with a bad tire your trap speed should be similar to what it would be with a good tire and 60 foot. Hope that helps. Ever since then I put on a 3' pulley good for 11psi and my tuner is giving me 25 degrees of timing on e85. The car no longer runs on summer tires because it will just roast them. The 19' drag radials are having problems keeping the power down in 1st and 2nd but on the highway in 3rd the car is an animal it pulls hard.
