I have a gmpp stage 3 pcm for 06-07. I have had a change of plans and do not need this any longer. It was installed in the car for less than a week. I am willing to let this go for $275+shipping. pm me any offers

 

tempting... the no/ac is bascially what is holding me back... Better tune over gm stage 2 tune?

 

im not sure if the tune is better or not, i didnt really run my car hard w/ it on there(i was having other issues) i think the main advantages are the 100 oct. mode and easy application of n2o.

 

CT has that pcm and he said (using his wideband) it runs leaner. I forget how lean.. 11s i believe.. so Im sure it makes more power plus might get some better mpg too.

 

 

Anything wrong with the pcm

 

there is a how-to that shows how you can bypass the no-ac

 

nothing at all, ive just had a change of plans, and the stage 3 is no longer a part of them... it was installed on the car for less than a week.

id take it right now but my stealership told me they wont warranty it

 

stealership never has to know... it is a 5 min. switch at most and you dont have to give them your vin# since you would be buying it used.
