Installed a Ball Bearing Arashi 20g. Today during tuning the turbo was overboosting to over 25 plus punds. Not sure why because according to specs, the turbo has a 1.1bar actuator on it, which equates to 15 psi. Is it possible an incorrect spring was used?

Been running mines now for 3+ years 30K+ miles with no issues.

Running EWG and meth injection at 24 psi making 415 whp and 380 wtq Dynojet (I have seen 440whp and 390 wtq on road dyno on a much cooler night).

Turbo is about capped out there in terms of efficiency.

Tuner says to go with td05 20g as td06sl2 is laggy for 350whp
But what about the ball bearing td06sl2?

i have the journal bearing with 11 blade exhaust and its about as responsive as the stock vf48...when it goes i am going to do the same turbo ball bearing and would expect it to spool a little better!
