I had some real quick questions about the Diablo tuner. So far I'm loving the HF tune in it currently running the 89 octane tune and the truck feel like a sports car loving it so far. Sean was and still is a big help getting me through all the steps big thanks to them at HF and Matt from moe's performance
Great guys!

My question is I already had my vehicle setting chosen to my truck and while I was on the computer I accidentally messed with it and once I put it back on the truck it asked me to select my vehicle all over again. So did I make a big oops? Or is that fine?

Second how do I set my tire size on the tuner itself to correct my speedometer?

Thanks in advance guys.

As far as whether or not you have to set it up to your truck again, I don't know that answer, but to set the tuner for your tire size, the tuner will walk you through it. You select the parameters you want to change. It's pretty self explanatory.
