I had Bret Barber at Airflow Flow Solutions, port my lower intake and supercharger case. Here are the results. Bear in mind that these pulls were done in 3rd gear as I have a 12' car and didn't get a dyno lock file for 4th gear before my "before" dyno test, so I dynoed in 3rd for the after numbers for consistency. I don't run as much boost as most with a built bottom end do, so I was unsure what to expect. I gained almost 34rwhp! Boost dropped 4lbs from 15.5 to 11.5. There was no ice used for the before or after. My modifications are as follows:

Stock 6r80 and stock converter (FTW!)

Thanks Bret!
