I went to DiabloSports' R&D to be a test of their Predator hand held programer. I got 12rwhrp and 20ftlbtrq. They told me that Chevrolet has tuned the SSR pretty good. By the way, stock it dynoed at 235rwhpr. You lose about 70hrp through the drivetrain. So right now they working on a marketable version for the SSR. Should be ready in a month.
