Let's hope for an answer a), since that'd be much simpler to diagnose. So simple - as someone already said - that any mechanic should figure it out immediately. These ecu-upgrades make me fear we have a case b) here...

It was asked earlier in the thread, and the OP said the engine is indeed revving up as the tach moves. Given that information (and assuming it's correct) the answer is so obvious I can't believe they haven't gotten to the root of the problem after this amount of time. :iono:
Of course, my service department has proven incapable of even properly performing a routine service, so at this point I guess I wouldn't be surprised to find out that they can't figure out a slipping clutch.
