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.
Long Island, New York
I like a motor and am used to one that will pull until redline, call me spoiled however I like em that way, best to drive before tiy buy,
