Unsure why car isn’t boosting properly. Wastegate linkages rattle which is odd as well as they’re a new set of CTS Stage 2+ turbos. Smoke test done and leaks fixed. Car still isn’t boosting properly.
Night and day difference between OEM DP and catless. Car feels good overall now. Not sure if we can get the turbos to spool a touch sooner? More for street driving use/throttle response. Thanks Ken. Again sorry for the fumble on my end.
