i want to know if you can get the stage reflashes done WITHOUT buying the whole kit. thinking maybe stage3 - stage4 pcm. anyone know?? thanks

 

As far as I know, you cant get the GM flash codes without buying the kit.

I know Intense and ZZP sell PCM's that are retuned and you can buy just the pcm.

 

will it increse power

 

.......?

Not without the mods to go along with it. In fact, considering most of the canned PCM tunes are for bigger injectors, the PCM will probably not like you too much if you try and run it with no mods.

If you want more power without a lot of mods (i.e. just from a tune) you're better off paying for an HP Tuners custom tune.

 

mods are CAI and Meth. Injection. we are looking at doing 60# injectors, 2.7 pulley, exhaust and then like a stage3 PCM.
