Tuning Problems

[gt5.0coyote]

Hey guys I purchased a 20x11 wheel with a 305/35/20 tire and emailed Lund for a tune revise and I got a email back saying to go into the tuner and adjust it myself. I have the older sct x3 and tried that and now at 6,000rpm I have a backfire. What happened?

the tune should not have changed.if your on the custom tune setting u should have settings to change tire sizes.

That's what we did. It asked us if we wanted to change settings and we clicked yes and there came up a bunch of stuff and revs per mile were one of the things. It then asked us if we wanted to save our changes and we clicked yes. We took it for a drive and kaboom.
