Cobb Stage 2 biotch!

Default Stage 2 - Is my boost ok?

I am reading 14.8 psi from my AP in third gear at full throttle. (Has been programmed for 1+ months.)

22 Degrees Celcius
50% humidity

Is this PSI good for the above conditions?

Thanks,
Matt

How many miles on stage 2? I think target boost is 15.8psi, +/-.5psi. If you just flashed to stage 2, give it some more miles. I'm currently hitting 16-16.5psi.

sounds a little low to me. isn't stage 2 16 + or - 5? I don't know for sure, but depending on what kind of gas and tune you're running, there could be more power to be had.

Just looked it up, it is 15.8. I think i was reading that low at first(14.8), which is actually the target boost for stage 1, and after ~100miles, I'm at 16ish.

Target is 15.8 +/- .5
I am using a 93 octane map on 94 octane gas.

I have probably 500kms on the tune.

Edit - Oh yeah, 3 inch downpipe, stock midpipe, 3 inch catback.

usuing 94 octane that's low. check your system for leaks etc, make sure everything is in proper order. If it is i would start with the waste gate (tighten it up). if that's greek to your search for WG arm adjustment in the 2.0l forum.

Def go with the wastegate arm adjustment...I always thought I had an UP leak because of slow spool and not target boost in 3rd gear. I tightened mine about 3.5 turns and WOW...what a difference...15.8 psi in 3rd by 3200 RPM...16.3 psi in 4th and 5th...

make sure you're looking at a high gear (4th) under load. It's hard to hit target boost at low load.
