Just so long as you stick with the standard 55psi regulated setting as the stock pump there is no need to change the tune.
However when you go E85............

Wouldn't hurt to log and send in before you go WOT, just to be safe.

A retune will get rid of the CEL's associated with switching to a return style system

There is your answer. He would know. But you could always trailer it back.
