im still having the same problem now just for haha's i pulled the mass air plug no change in the way the car runs i hooked up my old sensor no change could this be a problem or still a timing issue?
and what are the other mods done to the car, if its just a mild combo with e7s or gt40s etc, then i would consider swapping back to 19s, 19s can handle a mild N/A combo easily. to around 300 HP i believe.
to do what im going to say you have to have some balls. start the car, pull one spark plug wire off at a time to see what cylinder is dead. or if you dont want to do that you can pull the spark plugs and look at them. plus you should be able to turn the motor over by hand if not you have internal damage. in other words you have to rebuild the motor. with your set up you should be only running 19 ib injectors not 24 ib
