No boost creep on an internally gated bigger turbo, lots of knock in the upper RPMs. Turbo won't boost past 20 PSI, only spikes past it then falls. Having to run 780 cc injectors with a global setting of only -25% in DSMlink when it should be closer to -40%. 100% injector duty cycle needed to run only 20 PSI of boost. :uh: :uh: :uh:
I just found out my car couldn't hold more than 6PSI after performing a boost leak test at QPR. My EGR was leaking horribly, installing a block off plate from QPR brought the PSI up to 11-12 on the boost gauge. Then I found a couple smaller leaks in the piping and we had it at 18 PSI rock steady only leaking slightly out the BISS screw. Suffice it to say, this car needs to be tuned all over again which is a good thing!
