In my previous car (Mazdaspeed3) it was discovered that the computer would change the throttle opening (throttle by wire like most new cars) independent of driver input (in percent, 100% being full open) as the engine reached red line. With 280hp and frontwheel drive, one can understand why the computer would have some override capabilities in lower gears and speeds, but the throttle would be around 50% 500rpm before redline (driver is asking for 100%). Presumably it was a safety measure because of the high boost levels and high RPM, but does the V have similar mapping for the throttle? There was a reflash from a vendor called "full control" that kept traction/stability control features in tact, but when you wanted 100%, you got it. Interestingly the peak HP/TQ remained roughly the same, but both climbed sooner, became steeper in the midrange and flat all the way to fuel cutoff (vs. the stock bell curve). Clearly we are dealing with different vehicle architecture, but just curious about it.
