Well, as it turns out, a good friend of mine is building a BEAST of a Genesis 3.8 and invited my son and I to watch the car getting dyno tuned yesterday, which ironically, was being done at my tuners shop (he "shares" his dynojet with another shop nearby). So, while we were there, Paul, the owner of ECS showed up and, we went out for a rip in my car, while Paul datalogged. He changed some things, had me drive...changed some more things....and had me drive some more.
What he arrived at was, no matter what he did to try and adjust it, the wastegate duty cycle changes literally werent doing anything, one way or another. He also, from the passenger seat, very much heard the noise I was talking about, and said that he felt that the wastegate was not functioning right, thus leaking boost. So, while on paper, at WOT, it looks pretty good, at anything less than WOT, its not holding anything. He said that my TD04, at almost 100k has what he felt was a good amount of wear, especially after being tuned a few times. So, he gave me a few options:
1) Since I've spent quite a bit of money on dyno tunes, only to have the car run "right" for less than a month before the clutch went, I could find a second hand TD04 off a Forester, which they could literally install without changing anything ...or
2) Go for a whole different turbo setup, with new injectors, TMIC and a new tune- which I'm looking at spending a few months salary to do.
Right now, I'm going to proceed after option #1- I know its just a stock turbo and that there are no guarantees, but, after spending almost a grand on just tuning for a TD04, I'd like to enjoy that tuning....
