I recently got stage 2 installed and it pushed 14.5-15 lbs drove it around for about ~30mins and installed my 2.9. Upon start up I noticed it changed my exhaust note a little for the better and it built boost faster but it only holds a flat 15 lbs.Any idea whats going on or does it sound normal?

 

Yeah that may be right. Depending on altitude/weather it can vary. On hot humid days I can see 15-15.5psi all day long on mine, but here in Charleston we're also at sea-level so on colder nights I can see 17psi.

 

Yeah I just thought 1.06 drop would give me more than .5lb

 

Well it probably will. Check it on a colder day. Weather will make a noticeable difference on it (I'm sure you already know that, just reiterating b/c it happens to me too and it's easy to forget).
