Sounds like they don't have the wastegate duty cycle mapped properly for your uppers gears. And for them to push a street car to 28psi on the stock turbo on pumpgas is irresponsible and just plain stupid.

Just for comparison. My Evo VIII put down 303 with similar parts and a apexi AFC II map from Buschur at 21psi. At 28 psi it seems a little off.
