bbenny - Removing the boost cut, or more correctly speaking air flow cut, is not a good idea. This cut is put in place to protect the motor. The cut happens when your AFM reaches a certain voltage.. Getting rid of this cut puts a voltage clamp on the ecu eg 4.5 V... When your car flows more air than this voltage clamp the ECU literaly has no idea how much air it is getting and can only be mapped by RPM, or putting it simply guessing. The only accurate method of mapping above this 'boost' cut is to swap for an AFM that reads a lower voltage at the same flow, Z32 for example. A Z32 AFM will read up to 300 rwkw ish quite easily. I have tried mapping using this simple boost cut method and it can easily result in detonation in light to medium throttle applications and very cold weather.
