You don't need a shop to install a tune. You plug the device in and upload it. Really doubt they would install another shops tune anyway.Would any of them install the Palm Beach Dyno Tune ($319) for me on my DH? I don't feel like spending an additional $400 on a tuning device, not for that little bit of extra power. And Livernois' dyno report is pretty off-putting.

So buy one. You can datalog etc with them, you'll always have a copy of your tune you can reload or put back to stock...you don't want a shop just writing your ECU and sending you on your wayThat's the thing, I don't have a device for that![]()
