So my st165 sputters when it reaches max boost, and I'm not sure why. As far as I know, there hasn't been modification, except for a 3" exhaust turbo back w/out any Cats. It feels like its intentionally cutting the fuel when it boosts, but only happens when it maxes out. I'm fine running .8 bar on the original gauge.
Next, just today it started sputtering at low rpm. This doesn't adhere to the predictable, consistent nature of the max boost cutting. It feels like its not firing at random.
Third, something, possibly the rear diff, is howling above 3k. Doesn't matter the speed, its all rpm.
Does anyone have any ideas on possible problems? I've only had it driving for about 3 days and 300 miles since I sorted out all the electrical shorts. Will update wednesday once a Toyota dealer looks at it.
