NO2 question
Is it safe to just go full throttle and have it spraying between gear shifts? I have the original "timing tuner" but am not really sure how to program it. I know there are more modern user friendly controllers but, I don't eat nickels and $hit quarters.
Any advice would be greatly appreciated.

Here is the instructions on the timing tuner box it’s a window switch too so you can set it to shut off before the shift.
