I have the same problem.
My 930 with K27, headers, larger half bay IC, new wastegate tested with both .8 and 1.0 Bar springs, new fuel pumps, injectors, new cam timing etc.
Still the power curve drops off after 3000 rpm in all gears. The new K27 7200 spools up quick around 2500 rpm and the wastegate dumps heavy but I feel like I have to shift around 3500 rpm because I don't feel much of a power pull at that point. This is just after a major disassembly of the engine to replace a single cylinder after it cracked less than 100 miles after my shop installed the aftermarket intercooler, K27 and headers.
I wonder if I over boosted because of that work.
Any ideas because I am arguing with my shop now because I won't accept the car running so poorly.
All ideas are welcomed.
