Default tach fluctuation problem STILL HAPPENING - injectors???

I am having this problem with my tach and motor where when i am under full throttle acceleration my tach will be climbing up to 5k or something and then out of nowhere it will jump to like 8500+rpms. i know my car is not that fast !! and also when this happens the motor be like POP POP like i am pre detinating or something and i will go from boosting 7psi to like nothing. could this be a timing issue? or do i have a bad sensor somwhere? thanks

Stupid question: Is the ignitor the same as the ignition module?

If so I got a couple lyin around here from when my car was a no-spark.
It turned out to be the coil that Ohmed out perfect per the haynes manual.
