I think the +/- 1.0 PSI is with their SWG map. I was 3-4 PSI under on the regular wastegate and 1.5 under on the HWG map.
The part that really bothered me was that I had to be closer to 3,750 rpm in 4th to really start building boost where as I start building at almost 3,000 with the 3.11 map. That means a downshift at 60 miles per hour puts me in boost when i downshift rather then during the lane change when I need to pass.
Heres to hoping it gets resolved quickly : )
