[QUOTE="bunits19714, post: 15467823, member: 171001"] add 3 psi to your tires they are to low for your hp levels- mayb 4 you should be pulling 1.85-1.88 and the car should not even be able to spin those tires you have at the track at you hp level, what was your DA, with your mods and tires you should be 11.95 to 12.15's . Until you add a converter then you will have traction problems- is your front sway bar still on? the car drives fine with out it especially with the stiffer rear control arms that you added it tighten the car up so there isn't as much body roll. Try staling it as hard as you can against the brakes and let it fly- thatwas the best way mine when stock converter and NA launched- I heard the 11 converters are slightly looser than the 13-14's and usually generate slightly better 60' by a few hundreths. I ran 12;30's tune only with the factory p zeros all seasons at 25 psi- and only went to mid 1.8's going to a drag radial( a lot more consistant ) at the track but disappointing for the 650 I spent on the 18" radials, This was in good air thou, 0 to -500 da.
