Race, 1-2 shift will spin for a full second and practically get sideways. I can also chirp when shifting into third at 60+mph. Bama tune couldn't even chirp the shift into second always. Downshift delay when mashing it in drive is also greatly reduced. Keep in mind this is on my all seasons though not my summer only tires. When I get a day off school and work and the track is open, probably in like 5 years lol I'm hitting the strip.
