cowboy, I'm interested in what you found! I'm having exactly the same issue. and guys its not that he's driving it like a rocket, (at least on mine) when going thru the gears its really sluggish and then out of the blue without changing pedal position it will throw u back in the seat instantly and reach shift point ( as if you were in a rocket) and I noticed lately that it is running higher boost on flat roads like 20 to 25. It still achieves full boost (about 37) but takes longer to get there
