OK If i go WOT the car just sputters jumps and doesn't want to pull past 4000. If i hold it quater throttle it runs throgh like normal. Im running a KKK stage 1 and an APEX PFC tunned by SR morotsports. Not dyno tuned just recived it based on what i have done to my car. I am currently making 5 psi with no boost controler. It holds steady in both situations. I am pulling my wastegate line from a nipple of the pipe from intercoller to turbo and my boost gauge from the same spot. Any Ideas? Please Help.


Edited. I also have an APex FMIC

 

Fuel cut?
