I have a 2006 f250 5.4 with a flowmaster 10 series exhaust and a k&n filter. i love the 91 octane tune but we only have 89 and 93 here so i had to turn it down a little to be safe. is there any waythat yall have a 93 performance tune for my truck? thx!

Just use the 91 tune. As long as youre using 93 the 91 tune will be fine.

Does the exhaust and intake make a noticeable difference?
