Car is running brutal rich

[TweekedGT]

I can't figure it out. My car now that the blowers is on is running super rich. I haven't got it dyno tuned yet but my tuner sent sent me an SCT file that he says should make it run almost perfect. Fat chance. It runs worse than ever. I just replaced my front 02 sensors last night becuase they looked like they were in rough shape. I drained the oil last night too and there was gas in it. Too much cylinder wall wash I guess. Any ideas what could be wrong? I've checked for Vac leaks and can't find anything. I guess it just needs to be dyno'd real bad . I haven't run the car with the new 02's on it yet. It's one of those catch 22's. If I run it and it doesn't work I'll probably foul the new sensors and get more fuel into my oil again but i have to try it to see if it worked.

Are there any changes you made that your tuner might not have known about? MAF, injectors, etc.

Maybe an injector that's stuck open.

did you get a new MAF sensor recently? could be that. maybe a map sensor also

Go over every connection to make sure none of the pipes or couplers came off. It wouldn't hurt to hook up a mechanical fuel pressure gauge to verify you have the correct fuel pressure.
How does it run if you unplug the MAF? [Don't drive it with it unplugged, just try it while it's idling]
Where did you put the IAT, or did you hang it in the fender well?
Everything may be OK and the tune is just too rich, but it wouldn't hurt to check everything over anyway just incase.
