Curious about adjustments

[leroberts]

I have pit the original premium fuel performance tune back on the truck. The questions I have now is what would cause a belt sqeal right as the truck shifts into 2nd under hard or moderate acceleration?
Any ideas?

nothing in the tune directly, its likely a result of the quicker/firmer more positive shifts...

I agree sir. Just was wondering how it may be fixed. Maybe a new belt? Im not sure and was hoping you might have seen this before.

The more I drive with this tune the more I like it.
Thank you for your prompt respnse sir. Just awesome to have that support behind an already great product!
