I recently got a turbo setup for my GSR, it ran fine the first hour after tuning it. Then at 7K rpm the tach would just jump all the way and bouce past 9K. I was told it is the ICM/ Ignitor, will replacing this part correct the problem. Also the car seems to be slower now, is this also a ICM problem? The coil, cap and rotor are new.
