Flashpaq and tune up question

Hey guys, I forgot to reset my Jeep to stock before I took it in for plugs and wires. When I pick it up latter should I reset to stock then back to 87 tune? Really wanted to do the plugs and wires myself but had one plug that was stubborn and didn't want risk breaking it off. Thanks in advance!

You would be ok, technically you don't need to go back to stock, make sure they're not flashing your PCM, typically I ask the writer not to flash anything in my PCM without me signing up on it. If you're getting warranty work, make sure to flash back to stock before you take her in.
Have fun.

Hmm, If I get a Flashpak, is that an issue for when you take the Jeep in for service? Does it have to be set back to stock all the time?
