Default Breaking up under full Throttle

I am getting some breaking up under full throttle. Part throttle is fine and when the engine is below 150 degrees. So it runs fine first thing in the morning.

Mod's SPL Long tube heades, SPL 1.85 rockers, 3000 Vigilate Stall, MTI TB, MTI Tune, K&N Filter Kit, and LS6 MAF.

I have checked several things (Changed plugs/wires, Fuel pressure fine, No Codes, Re-installed stock MAF, TB to try it and it still breaks up) Anything I can change with HP on Tune to help.

In the mourning youre still in closed loop and fuel is being enriched. Sounds like you need to recheck your tune.Your fuel map may be a bit off.

I would also make sure you aren't having problems with your 1.85 rockers...

I had similar problems. Turned out to be a broken valve spring
