Hey - has anyone on this list installed a GMPP stage 3 kit +Option B yet? Is the 20hp gain noticeable? how difficult is it to install? I heard the option b aftercooler is a bit tough to install. Not sure if I install this myself if anyone from the GM service department would even notice its a stage 3 to void my warranty--any stories?

ive found the kit from gm parts direct for less than 600. and CED has the Option B for 96. Also thinking of adding GMPP exhaust, but heard it only adds 5-8hp.

Thanks all,
Shaun

hey u going to uti? my buddy has a friend that goes down there and he was talking about getting a stage 3 balt dynoed last week?

 

i have that inter cooler with the over flow bottle i dont think you get 20 more HP it just bleedes out all the air . it will not void you warranty if you dont buy the stage3 PCM they want your VIN to buy the PCM that will void your warranty that is what gives you the 20 HP not the dule pass end plate ti just lowers intake temps very little HP gain.

 

Shaun,
double check your finial price gmpartsdirect before you buy it.
