If you have it floored- there is ZERO difference. Literally, there is nothing the PBX can do, at WOT, to change how the engine runs - if it did, it's all in your head. Maybe there's a difference in throttle response, but that's mostly because it makes the pedal overly sensitive to compensate for the conservative factory tune. Given the I/O of the PBX, there is just no way it can do what it's claimed too - the only other thing it can do is change the AFR, but since it only has TPS as an input, it's only doing this at WOT - and the 330i does NOT need more fuel at full-throttle (you actually lose power).
