Superchips Microtuner in Performance mode at high elevation
Some insight would be great here.
A local Superchips Dealer told me that I may experience some knocking if I try to run my 04 FX4 in the performance mode (91-93 oct). What do you guys think? I spoke to Superchips and they said no way. I am at 5500' ASL. Any info would be appreciated as I am on the last quarter tank for the 87 octane and I really want to try the 91-93 octane. Thanks JP

I have had my truck set on the high performance mode now for about a month. The only time I had any knocking was when I first started it up after the install. Since then no knocks and the truck runs get. The only thing I do not like is when it is time to fill up with the premium fuel. But with the differance in the way the truck runs between the 87 and 91-93 settings I am willing to pay the extra for now.
