car is v4 wrx sti
Mods zre fully forged, link g4, twisted turbo, aftermarket fuelling, fmic, cams.
Prob is that on very light throttle it misses and hesitates but once you put foot down its smooth again and then randomly pops and farts on boost in random gears. Ive changed the plugs, coil and ignitor. Still no change. Theres no cel or any codes on the g4. I dont know whether its a crappy tune thats causing it or something minor. I thought plugs were first obvious thing but no luck. Im not too sure where to look next, ive searched but noone seems to havea misfire on light throttle.
Any help would be mint
