PCM tune or Handheld tuner?
I have a Nelson tuned PCM. Will a handheld tuner give me the same power? I have added factory electric fans and want to enable pin 33, and have switched exhuast. So I was going to send PCM back to do these changes, but would rather do it myself than send PCM back every time I do another mod, if I can get the same power, as I plan on adding a air intake, etc.

Why Can't I stop the mods!
