I've seen a plugged intake cause boost oscillation that isn't really evident until you add a tune, but I assume that's not your issue.Uberhare said:I can hit almost 25 psi anytime I jab the throttle. The ECU pulls back pretty quick to 15 then back up to 20.
Car operates fine with stock chip and big injectors. I've checked all of the control lines AND tried another control valve. I think it's something in the software.
Time to talk to Jeff...
