What injectors and pump you usin? Big injectors cause high timing but your case is ridiculous. Just add more fuel is the only opinion i can give you.

I got fic 660s on the stock pump,tried 2 richen it up on maft as well as afc no dice

650s will really raise your timing and the stock pump probably isnt sufficiently feeding them. Did you have this problem when you were running the stockers?
Oh yea, does the car feel like its bogging out at all cause it could be that you're too rich as well. Sounds dumb, but that may also be the case.

Runs tight ,Ive clowned a few v8 mussel heads ,but its lean 4 sure under full boost.

Well then either rewire the pump to try to squeeze more out of it or splurge that 100 bucks and buy a walbro or something of that nature.
