If not you have the incorrect scaling on your map sensor.

2. Talk to your tuner about the health of your car, not a bunch of idiots on a forum that are all guessing.

You have replaced your MAF housing, your injectors, your pump, and your manifold pressure sensor, and o2 sensor housing. You know... the majority of the equipment used to supply fuel to your vehicle.These all need to be carefully calibrated correctly and asking a bunch of random people on the internet is just second guessing your tuner and beating around the bush. You should be asking him/her what to adjust and verifying your components are correct. If you came here because your tuner is no longer helping you then you need another tuner. However I highly doubt that is the reason you are posting this thread.

You obviously have an issue considering your manifold pressure is well beyond 2x normal at idle, your stock o2 is maxing out on lean (as in it doesn't read fuel or is really running ungodly lean), your injector pulse width is very high at idle... none of this makes very much sense if the correct calibrations were entered into the tune.

i have notified @DeliciousTuning regarding my concern awaiting for a reply. just trying to self diagnose my vehicle to see if im missing anything..
