Took to a pro tuner and they did compression check, leak down test, checked the valve seals. Everything is good on the motor side. As a last resort they ask what oil I'm running and they say a lot of Subi motors have problems with mobile 1. Fill with motul race oil and no smoke.
Just wondering if anyone else has cone across this problem?

What turbo do you run? Ball or journal bearing?
If ball bearing, do you use an oil restrictor in the oil feed line?
Could be the problem.
