Did you change anything with the gears to notice anything different?
I just put in Drive Gears yesterday.. Accleration seems crappy, put after about 4k RPM I can tell a difference.. Just took it on the highway and it seems to get to 100 alot quicker... Still pretty disappointed with acceleration though..

Funny story while we were working on my car last night.. After we finally got everything done, we jacked up the car in the front, so we could spin both tires and before we tested it on the ground.. Friend was revving my car, and then let off.. and then my tires just like, seemed to lock up.. So we put car on ground and tried to drive it, but it barely budged.. We thought maybe parking brake locked up or something... Drove it around the block, and it shifted gears.. That's when we realized all that happened was the car tried to shift gears while jacked up, and was still in top gear when we put it back down.. Scared the hell out of me
