I think you might have gains temporarily, but over time as the engine "learns" how the driver's drive, i believe it adapts the engine to it ... I am just wondering if I drop 500 bucks on a tune, that it won't last temporarily and then I have to continuously reflash the CPU each time.

Please let me know how Tony has address this issue or if its even a issue at all.
