alright i just installed the gm stage 2 kit and got the flash.. my question is at what rpm should my boost gauge hit 14-15 psi?

 

conditions vary, why?

 

well im only hitting 12 psi and im wondering were the other 2 or 3 were.. maybe i thought its just the tune wasnt right? idk i was in 3rd and hit about 6k and only at 12.5ish maybe less

 

12 psi is right for a stage 2.

 

you installed the pulley right?

nono

 

I was trying to end the thread, becouse it seems like he is going out and trying to stare at his boost gauge while flying down the road.

Well, I saved a life.

 

ya the stage 2 pulley 77.9 is in.. idk im kinda new to the stage upgrade

lol no its not like that hahaha.... open spot hard to explain

 

oh lawd hahahaha

boost bypass valve, search

 

ya iv done that search.. that was prob going to be my next mod

 

Wow, you really are from Alabama.

Anyways OP,

Who installed your kit?

 

no, your bypass valve is likely sticking open. you need a new one, dont do that bypass mod you are tuned.

indeed sir

 

gm installed did for warrentie purposes..

sundevil how can i tell if it is leaking for not?

 

gotta pull the blower, just take it back to the stealer. your ic pump is working correct?

 

Take it back to GM and ask them to do it, its under warrenty they gotta check it out.

Alot of things could mess with the PSI.

Belt slippage..By pass valve.. are the only things that come to mind.. but im not a car guru.

 

ya.. theres no codes or anything.. so call the dealer who installed in an ask them whats up?

i mean it still pulls hard just seein it hit 12.5 not 15

 

yep, could just be a bad boost gauge. the car feel any quicker than stock?

 

lol omgosh yes lol. ya i work at a nissan dealer ill talk to them about it and see if they can find the problem or problems first

 

9k.
















but no seriously your bpv may be sticking open/opening too early. it its just bad timing that it happened to be right as you got the gms2 installed. mine was stuck and it was at 12psi. its actually a common problem.

 

dam.. well i bought the car about 1 an a half ago and there was stage 5 intense on there lol in it was clearly pushing about 22 but i immeditly took it off.. but ill check it out

 

22psi huh? what kind of boost gauge are you using again?

 

Hey dude where in IL are you?

I saw u selling **** on craiglist.

 

stage 2 is 15psi, maybe gm didnt put on a new belt or didnt sell you the pulley

 

15 psi is a bullshit number man. With a full exhaust and other supporting mods flow increases and boost decreases. With a stock header/dp/catback ya i boosted 15 with a stage 2 car, 12 with full 3".

 

The stock boost gauge but it had a 2.5 on it so I just kinda did the math.. But I live in st Charles ya i posted some stuff up there.. An I don't have any exhaust mods on there

an i put the 3.0 pulley on myself so it wasnt the pulley
