what does the 04 supercharged top out at? i got to about 120. stock no mods

 

is the pcm the little module found under the hood in the bottom of the airbox? i have a 2001 monte carlo ls, 3400

 

I've had my Indimidator SS to and held 125 stock. Since the mods, I hit 135 and was still going when I back down. Caught some cross wind. I think it will hit 140. I intend to find out this summer.

 

is the pcm the little module found under the hood in the bottom of the airbox? i have a 2001 monte carlo ls, 3400.... i wanna send it away to be reflashed

 

That's the PCM indeed. Make sure you disconnect the negative on your battery before you disconnect the PCM. Your car will not function without it. I'd suggest you pick up a stocker from a wreckers, and send that in instead, that way you have a spare.

I've been 160+ a few times... with room left to go, it's dangerous past 120mph, and I won't try it again, especially with my 3.29 gearing... running in 4th gear at WOT is tranny suicide.

 

ok... thanks
