I recently had a bit of bad luck that killed my turbo, the small hose going to the wastegate broke and allowed me to over spool the turbo and pretty much kill it (at least I think thats what happend to it). I had serious boost lag, general lack of boost, and intermittent oil smoke that is now completely gone with the replacement turbo. I put a stock low mileage turbo on to get me back up and running, this turbo seems great except under gradual acceleration. When I am driving "normal" I experience a kind of flutter, or inconsistent boost feeling. Under heavy throttle it does great, pulls nice seems to do what it is supposed to. Can someone point me in the right direction? The car is mostly stock, I thought it was 100% stock until I did the turbo swap & took the heat shields off to find an aftermarket down pipe with no cat and resistors wired into the O2 sensor.
Thanks for any and all help
