Holley HP EFI TBI Olds 400 v8

[67w30]

I'm having trouble coming up with a good timing map for my setup. Any suggestions or tuners in NJ that could help me out?
Car runs great but my mags suck and I know I had more out of the engine with a carb n distributor. Love the self tuning but the set timing map has me unsure on how to get more out of her. Thanks! First EFI install and tuning.
