no timing advance and misfire

[avaien]

Whats up guys. My car has 750cc inj, 42 psi fuel preasure, no boost leaks, 272 cams, 57trim turbo and ecu+ with other supporting mods including head studs. So after the cams, timing belt change the car started stuttering and misfiring whenever I revd it up past like 6k. I log it and the timing doesnt advance which explains why its not makin much power. I log knock on the ecu plus and it goes up to 1.25 volts. Im not really sure where to go now. Im thinking the ingnition spark is not strong enough, the timing is off, or something else.

I'm assuming you checked the timing marks. Spark plugs (Colder Plug) /wires?
