running not strong up top I had a major power loss problem which turned out to be a a dirty maf along with bad gas. The car runs good down low but at high rpms it just doesn't have the go. The motor is revving up slower. No codes. Fuel filter changed 1 month ago. Plugs, wires maybe or is the maf bad even though I cleaned it?

Muffler in midpipe? How confident are you in your exhaust
system? Backpressure kills top end.
Use your Predator, if you have no other option, to look
at the fuel (by O2s) and spark and KR, see what you can
deduce from that.

if you have a friend with an ls1 car, try swappin mafs and see if that cures it. you could also try some fuel system cleaner like Seafoam. also check/change your spark plugs possibly. even if thats not it, it can't hurt anything.
