Hey guy's, out of no where, my perfectly running (so I thought) sr20det redtop engine is giving me a headache... Here's the info on my car:

car ran great before my problem
stock sr20det maf/injectors/t25 (14psi)/ecu
upgraded full exhaust, fmic, blitz bov, 255lph walbro, avc-r

I was driving around, then bam, felt like i was running on two or three cylinders... Here's what i've found out so far...

compression is okay across all four
all coils work and give a spark
dont see any vaccume leaks
injectors all work
timing is in order
mafs working

If anyone has any possible answers or help, it will be greatly appreciated... And here's whats happening while its idling:

yes, it kinda sounds like an wrx
smells like its running rich
spark plugs are near black in color but are gapped fine
theres no water in the oil, no all white or black smoke at the exhaust
car idles at 800rpm

What could possibly cause my engine to sound and feel like its running on 2-3 cylinders? Please let me know asap, thanks guys...
