i have a b20z with b18 head and y1 lsd boosted at 8 psi. My car has p28 chromed although i have yet to get it tuned. i've got about 1000 miles on setup. While in neutral car only revs to about 4k but in gear it will go to redline. I'm confused. also if any one has any parts such as, victorx IM, 550 injectors, msd ignition, msd blaster coil, and an wide band fuel/air ratio contact me 217 520 9103

 

launch control?

 

sounds like a 2 step rev limiter. just get the car tuned asap. driving witout one is asking for trouble.

 

Launch control wouldn't work while the vehicle is in neutral.
