Under WOT car Accelerates then Deaccererates

Its really wierd what happing when im under WOT my car will pull hard then, a split second later i feels like i let off the gas to 3/4 throttle then to full throttle it will do this VERY rapidly all the way through any gear, its really slowing my car down.

boost is a steady 11.5psi running rich, it just started doing this lately and i have no idea on what it could be

any idea would be a help.

Sounds like fueling. How do you know you're actually running rich? Wideband?

its not bad to max out your injectors :P there was a thread about it a while ago. the gas tank was full. i dont know about the fuel pump but i think it might be that.

?


Sounds like you are running a PFC, try changing the duty cycle (% number) on the wastegate under the boost setting. With a stock wastegate if you don't get the setting right it will cycle the wastegate to try and keep the boost as set.

Hope this helps
