OP,
When you installed headers your exhaust became lower and/or sagged. Its now hitting at the tunnel brace or diff. That metal on metal noise you're hearing? It's metal hitting metal. The knock sensors in your engine hear that and think its detonation thus pulling timing. Its only happening under load because thats when your drivetrain moves the most. When it pulls timing you feel the weird underpowered fluttering sensation. There is nothing wrong with your tune, I'd bet you $1. Its doing exactly what it should be doing if it sensed detonation, which is trying to save your motor. The sensor is just too dumb to know the difference between banging metal on metal and detonation. Fix the tunnel brace issue, problem gone.

This post explains your issue 100%. Under hard accel and load the engine is twisting enough to cause your pipes to contact the cross brace. Put some washers and longer bolts (if needed) to fix the contact issue.

only reason I suggested it was that I broke one while attempting header install on my '95 LT1... that car was a beeyootch to install headers.

melted cats will reduce power. The higher the gear and stronger the load the less power.

My first thought is a tune.
