Just an update... It made the journey to Washington just fine. Total weight was just shy of 14,000 lbs and it still averaged 14 mpg averaging between 60-70 mph...
Here in Washington, I have just touched the 20 psi boost mark in 4th at WOT and 3000 rpm but it typically only sees 12-15 psi... The wastegate is set to 20 psi so it rarely even opens. No haze at all when cruising and having to pass someone at 60. I will have to get pics up of the current setup.
