Have o7 v8v with am power upgrade. Have experienced the right turn engine momentary cut out once (sweeping right hander wot.) Has anyone experience a slight burst of power upon release of wot to shift while in a straight line? I am wondering if they two may be related. I plan on experimenting with varying fuel levels. Any input would be greatly appreciated and also, if anyone had the fuel vapor line fix done what it runs and if it worked to solve the problem completely.

 

May be a boost in power from a lean condition.

 

I had an 07 Vantage that would have fuel flow issues under high G conditions on the track, creating a momentary power interruption that would unsettle the car under certain conditions. It was only an issue on the track. After researching this forum, I discovered there was a known issue with the early fuel tanks of the Vantage and the only solution was replacement of the fuel tank. Fortunately my dealership was very helpful and I was able to get the work done under warranty. Good luck.
