but does anyone here know of any chips or tuners that would work well on an 05 monte carlo? My gf's brother has seen what I've been doing with my 150 and he wants to get bit by the bug too. I tried looking on monte carlo forums but they all kind of suck. This is by far the largest wealth of knowledge i've found online so I figured someone might know something. Thanks in advance.

 

The only one I know of is Hypertech. they have 2 models for that make/model
here is the links

monte carlo SS

these are both dyno charts

 

Tell him to trade it in and get an 06 or 07 with a v-8, sorry guys, the monty with one of those rules, a v-8 in a 2dr, what a concept. But I second the Hypertech, I think SLP made one too, or Superchips, someone made another I'm pretty sure.
