Well I only have the stock gauge right now, and my mods are as followed:
-K&n filter
-3 inch downpipe(wich then connects back to the stock exasuht and catlatic converter)
-A carbon fiber muffler(not sure as to what the size on it is??? :dunno: )

Anywaysd my boost gauge when i floor it reads up to 8 psi but then goes down and stays at about 7 or 7.5 psi and will hold there.

so I have a few q's:

1.) How accurate is the stock boost guage(I know its not accurate but might as well ask anyways get some ones opion)
2.) Am i boosting at a max of 8 psi or 7psi??
3.) also how long should it take for the ct-26 to spool up?? Either im expreincing a bit of turbo lag or the boost gauge just takes time to respond or then again i guess all turbo take a second or 2 there power isn't instant.



thnx a ton for the cooments/info :hug:

1: Not at all. Get an aftermarket gauge
2: Depends on the downpipe. I'd say between 7-12psi.
3: You should be fully spooled a tad before 3000 rpm. This all depends on how healthy your engine is. Between 2800-3200 and you should be fine.

the gauge takes forever to read the pressure. invest in a boost guage. then get the rest of your exhaust 3"
