After 2 long day/nights - its running with boost. 2 very short shake down runs shows its behaving, now the tuning starts.
The wastegate is opening at 8 psi which is fine for the early stock engine. I got off the throttle almost right away when the boost came up - but the turbo spooled enough to be noticeable. Once I get the tuning done I'll do a video and post it.
One thing that is noticeable the engine is quieter - the intake noise that used to be quite loud is gone. The exhaust it reasonably quiet at idle - I was concerned it would be loud as the exhaust came off of a duramax diesel (4"pipe), once moving its quiet like a new stock truck.
