Ka24de-T random miss fire

[sid_s13]

Ok so as title states it's keeps having a random miss fire whenever it feels like it. It's really annoying motor is fully built cp pistons eagle rods bc stage 2 cams and valve train, jgs log manifold and 40 mm waste gate gt3076r , 1000cc injectors on e85 for tuning using a aem ems stand alone 2 bar map sensor and a aem iat sensor

it randomly sends the spark at the wrong time. the tuner set up a tune up to 3k for now so I can drive it

I've changed the spark plugs, wires, cap, rotor, coil, ignitor chip, and distributor and still nothing

Any help is appriciated!
