Is it running noticeably worse? Bad throttle response, dead spots, surging, and so forth? If not could be a bad O2 sensor? Maybe try free air calibrating it before replacing it.
Also need to know what EMS you are running and your other mods.

you don't mention it, but are you running a powershot? What's setting on rrfpr, is rising rate enabled?
which AFR gauge/sensor are you running?

You'd have to be running lean running those OEM injectors with an ET 18 wheel. I am at the max duty cycle with the ETSS low boost wheel at 12 PSI/8300 rpm and the OEM injectors. Guys and Girls nI know have run lean with even the low boost ET wheel at high (8700 rpm) and easily need the 1000cc ones for the ET extreme 15.5 psi wheel so you are way over with stock injectors and the 18 PSI wheel,Throw a set of 1000cc ones in and all will be good at WOT but you will have to tune them in..... some how or get the reflash reflashed for the bigger injectors.

I currently dont have a boost gauge, but i feel as if after a certain rpm or maybe boost lvl, the ecu or map sensor has gone nuts and cant figure out to add more fuel or what not, a freind suggested it might be the map sensor.. what do you guys think? Is there a way I can eliminate that from the equation with out buying another one? lol Thanks for all the reply's
