Installed a new v3 vortech 6psi. Had issues with idling at first. I was able to fix it with moving the valve cover breather to the inlet tube. I still have a problem with bogging/missing. I am using the the fmu with all new OEM ignition components, and Lowered the gap on the plugs. i notice it more when i let off the throttle and then reapply throttle. I have researched the forum but i am out of ideas. Not sure if it is fuel,ignition,vacuum or possessed. The car did run fine before the install. I would like to get it tuned but i believe this problem would still be there with a tune. Plus money is short right now. Any help would be appreciated.

Only other mods are cobra intake and full exhaust. I do have a AFR and it shows lean during this problem.
 
so you have a wb 02 and it shows lean during re-accelleration? do you have a boost gauge and if so, is it showing boost during this instance? are you running stock injectors...if so with what fmu dics?
 
I do have a boost gauge and fuel pressure gauge. the car is not in boost during this moment. Fuel pressure does increase also. This problem occurs during normal driving. I have attempted today to isolate the egr and I unplugged fuel evap from the upper intake, did not work. I also did a code check which showed 94,44,34,12. I have removed the diverter valves and plugged the vacuum lines. Isolating the egr caused code 34. Number 12 does interest me, I need to research this more. Any advice would be appreciated.
