Back to Stock on Upgrade?

[vernonator]

I am getting ready to have my catless-DP's installed (YEAH!!!!) and have the tweaked tune from Livernois. Do I need to go back to stock before applying it or can I just overwrite the 4+ 93oct version on there now?

Thanks all!!!

I'd check with Anthony at LMS to be sure for your version of the MyCal...

As far as purely tuning the answer is definitely no since it is an overwrite of you ECU programming.

That said.... the stock tune on the current no touch MyCal is downloaded from the server rather than copied from your ECU with the current no touch MyCal... so you always have it as a backup.... the availability of the stock tune on your device is the issue to be sure of.  So.... if they send you email files to load into your tuner check with Anthony.

It never hurts to put it back to stock before loading in the new tune. But you do not have to.
