Hi Chris, question for you. Did you change your spark plugs as JB4 recommends? Only wondering how it performs when stock plugs are used and if they are needed. I want the tune but do not want to dig into the motor that much.

Yes, I did change my plugs. I consider it a requirement and not a recommendation IMHO. Zero issues so time/money well spent.

Here is the method and tool I used:
