i just installed my autotrans interceptor on my cobalt.. i love it.. i still have yet to mess around with tuning it in but from the setting it is on now i feel the gears kick alot harder.. i found it on e-bay used for $75 not bad at all..

I actually chirped my tires when i hit 3rd gear.. granted it's cold out but it's a hell of alot faster off the line
