2002 Chevy Camaro V8 Two Wheel Drive Manual 91k miles

I have a scanner with live data and the fuel trims are a little lean part throttle and wot and the spark plugs confirm a lean running motor. Also about a 4 mpg drop and lack of power. I have tried another mass air sensor, tps, fuel filter, tested fuel pressure=good, and different fuel additives to with the gas. Both sides are lean with the driverside showing leaner. 0 codes.

Has this engine been modified and the computer not matched to richen the mix? LIke a different cam or headers. And check for a vacuum leak. Maybe the leak I to big and the compter can'tcompensate for it.
