Hi all

After doing a search i couldn't find a similar case to refer to to here goes:

Basically i was giving it some beans on the way home tonight, shifting at around 4250rpm driving it relatively hard. Then i started to merely cruise for a bit in 6th doing about 90 (private road). Then i put my foot down to overtake and there was absolutely no boost at all! the car felt completely gutless.

The whole thing happened without any noise or drama so i pulled over, turned off the engine, turned it back on and normal service is resumed

Any ideas??

It's your remap overboosting and causing the ECU to go to limp mode. Check ECU fault codes and consult your tuner for a resolution.
