We want apples to apples. Anyone can purchase a tuner and tune it themselves. Obviously this a route most should take, but some don't have the time needed to actually learn how to properly tune. This thread is about a ZZP shelf tune. Not a tuning yourself vs a ZZP PCM.
Who has had a bad experience with a ZZP PCM? What factors played in it being "bad.". Specifically what was in the PCM that caused it to be bad? What was specifically done before the PCM was added and what was done after. What was the timing set at etc? Those are the items we are looking for. I constantly hear ZZP PCM's are bad yet no one has mentioned what specifically in the PCM made it bad. Love to here input as I have run 2 ZZP PCM's and neither were an issue.
Why is it junk? Did you have a personal experience with one? You cant state it's junk without giving reasoning behind that statement.
So you feel as though a ZZP PCM is junk as well. Why?
