Speaking of fuel cut/rev cut, i have now found that i have lost 1000 RPM (between 7K-8K). I had reset my ECU and all looked good but again the same issue no more then 1 week done the track. It seems to happen when i lose traction when hitting lift in 1st gear. Can someone please help and advise as to why this may exactly be happening and what a possible fix would be. Will be taking it to Toyota next week but still very interested as to why this happens.
