On the minus side, the tune seemed to cause the cruise control to not work correctly; it would allow speed to sag until the cruise control dropped out.
"Your Mileage May Vary" seems to apply here. I ended up deinstalling the tune and selling the unit in the iRV2 classifieds.
Thanks for your thoughts
Banks and UPFORD Ultra RV have tuners too, so far I've found. They look the same, and may be the same.
My shop has a lot of respect for Banks. Still researching
Btw, looked at the K&N air filter shocked how expensive it is but on other hand isn't everything rv $100, $500 or thousands?
