Yeah she seems to whine pretty good, dont think she has much whistle
And first thing I'm replacing is the manifold to see if that helps cool the Pyro down, next step I'm upgrading turbo. And I want to check to make sure the IVAs have been backed off even tho it's deleted. I always get a check engine light that comes on but with no faults amd when it does I'm some what derated to about 21 or 22 lbs of boost
And the surging happens when it's powering up amd seems like it's fighting for fuel or looking for more power and can't find it. Not shifting gears tho

I’m surprised much others haven’t chimed in about your issue. Those SDP series are complicated.MSQUARED Thanks this. -
Yes that will help You should be seeing 35-40 Psi for that hp level Low boost will account for High EGT forsure but theres alot more things that can cause high EGT as well but low boost is bad
