Okay so I switched my map sensor now when it hesitates it seems like an ignition issue. It doesn't lean out now and at 4500 it starts to miss fire like a rev limiter but my air fuels are normal.

 

Tested fuel pressure today and it is 13v all the time. I tried another resister relay as well no dice. I'm going to check if the secondary injectors are functioning tomorrow. Probably with an led

 

Moved my grounds again checked all my injector wiring cannot figure this out my air fuels are all sorts of off. I should be runnin pig rich but I run 13s at boost. My wall is now at 4500 rpm on the dot. Car runs great under that point. Fuel pump has full voltage even when the hesitation hits. fuel pressure al is good not sure about when it hits its hesitation no easy way to tell...still think my secondaries aren't coming on but it feels like a rev limiter...sometimes my air fuels go lean other times they are fine and it is like an ignition issue...timing? Thinking maybe I put the timing gear on the e shaft backwards...but that would be a rookie mistake... Anyone have any idea?

 

I had similar issues when my Omp took a dump. Kills any ecu you put in it. Got rtek with Omp delete. Car runs beautifully now. Tried everything and it was a simple chip.

 

Mines s4 though:/

 

Well i guess that omits my idea! Any ideas everyone?
