Same thing as my last log, target boost is made on throttle tip in but quickly drops to 12-13 psi up to redline.

In this log, I continue to see low boost up to redline. The car is targeting higher boost in the midrange that it simply can’t hold. It holds fine into high RPM though, producing impressive high RPM boost numbers for a stock turbo car. It currently has VRSF Chargepipe, downpipe, 5” intercooler, TIC pipe, and Turbosmart VR9 Dual Port diverter valve.

The first log on 7/31 we see fuel pressure oscillate. The second log on 8/29 we see throttle closures, low boost, and lowered fuel pressure
