We discovered issues with the stock BOV opening at 5psi. This will be fix.

Update 2017-03-17
We are still suffer boost issues and need to review for exhaust header leaks, including the wastegate operations.

A new Turboback system was installed and all flow issues been fix. Tuning has restarted and we are now reaching MAF limit and will blend to VE very soon.
