Is anyone running the boost bypass mod with the stage kits reflash and a smaller pulley? I have not really looked to see if it makes a difference, just wondering if anyone knows for sure?

 

That's an awsome question, I would like to know too. The only thing is I have stage 2 and during WOT! the boost stays at 15psi. The bypass mod has been used b/c some peoples boost would fall back down to 12.5 after a few seconds. Maybe the gm reflash fixed it?

 

imagine the boost keeps building and building to redline
someone with bigger ***** than me has to try it lol.

 

your only getting 15 with the stage 2?

 

The reflash removes the bypass limiter, with a 2.7 I boost at 140 Kpa at redline.

 

i need a smaller pulley, sean where did you get yers and which is best for everyday driving?

 

Holy **** thats alot of boost.

Holy **** thats alot of boost.

Holy **** thats alot of boost.

Holy **** thats alot of boost.

Im getting 115 with the 3.

 

Yeah the 3" pulley gives you 15psi. Stock is 12.5

 

15 is kinda low. 115kpa is about 16.5.

 

BLKSS you have GM stage 2, what do you mean it sounds low? That is exactly what we are supposed to get. If you are getting more with the 3" pulley, your cat is blocked up.

 

there are more factors why he is gettin more psi than normal other than the cat.

 

Yeah it's probably elavation or something.
