Fuel cutting out of safety feature??

Inflaymes

I've noticed this problem since I've had the car but always attribute it to cutting out when the rear wheels spin. I never paid attention to what RPM i was in. Lately I've been getting on it at an on ramp or a straight away and with the traction control off, i noticed the car cut out at around 5000 rpms. I'm not even hitting redline and the wheels are not spinning that I'm aware of. New tires last season. Michelin pilot sports. What's going on? It does have an ecutek tune. I don't have any dash lights or any codes etc. It drives wonderfully other than that. Do you think it's actually spinning the wheels... Usually in 3rd gear and it's activating the safety cut out?

Any help or enlightening in the issue would be great.

Title should say OR safety feature...
