Let me know what you think.

If yes, my HP goals are about as much as the stock engine can handle so my question is should I go AFPR, or get a replacement?

If no, wtf do I do? I checked for vac leaks and found 1 tiny hole in one of the MAF solenoid hoses and fixed it. Boost leak test found all kinds of crap (throttle body gasket, upper intercooler hose, intake hose, etc.) - fixed. I've blocked off the FIAV, replaced the ISC, new plugs & wires, brand new ECU, cleaned the throttle body, checked the EGR, replaced the o2 sensor, replaced the coolant temp sensor... When I replaced the plugs, they all looked fouled.


Thanks
