what kind of improvement in e.t. would i see by adding a p.i 3200 converter,longtube headers and pulley,s? my car is an 02 gt 4r70w. my current mod's are mac cai,mac off-road x-pipe,3.55's and an nos noszle system and a diablo predator. i went to the track sunday and my best run on nitto street tires(not drag radials)was like this. 2.02 60'-----8.31@87 1/8------12.78@110.40 1/4. i'm hoping those added mod's will get me in the 11's! what do you guy's think?
