umm.... whats target boost supposed to be? i'm going to venture a guess, it's really hot outside by you?

MAF sensor?

Do you have a downpipe? If not, that is part of the reason.

I tuned a friend's WRX and we can't get over 14.5psi with Stage 1 using respectable Duty Cycles. We're going to tighten up the wastegate actuator arm in a couple days and retune. I want to see 15psi on a Stage 1 WRX.

What WGDC's are you running? Did you know that there is a relationship between the low and high WGDC settings? I had to set my lows within say 5 to 10 of the high to hit the "high" values (90 on the high, 86 on the low for example).

What values are you running?

The WRX doesn't have high and low tables. They just have a max WGDC table.

19psi on a stage 2 WRX? You're brave. I don't see running much past 17.5psi on those cars with a TBE.

That would be ok on the 2.0l WRX, but on the 2.5l I can't see the 13T holding 19psi for more than a couple hundred RPM down low in the RPM band if that.
