Message	The TT ECU ( Hardware ) will be selecting a 3 Step Fuel pump Speed.. the NA Hardware can only do a 2 Speed.. the TT ECU Hardware will shift off the NA Fuel Controller when the TT Hardware wants step 2. fuel pump Controller shift off, fuel pressure will drop and the car will stumble, then the TT Hardware will shift to Step 3, and the NA Fuel Controller will shift back on. You dropped in a NA ECU to test.. was the Injector size programmed properly into the NA ECU prom?.. if not then you did a mixture change as well..
