Well for starters the car has a forged motor with 4000 miles on it since the rebuild, FMIC, header back aftermarket exhaust alos a new turbo. For a while i was having an issue where the car would start to idle surge on cold start up's to like 1500 then down to almost stalling. After replacing the coils, plugs and wires it's only done it once since then. I'm althought still having a low idle issue but also seems to be only boosting to 3 or 4 psi then picking up the higher in the rpm's you go (but doesn't always do this). Any advice would be greatly appreciated.
