I have an 05 Ram 5.7 4x4 with flowmaster dual exhaust and a superchips flashpaq 3865. I have always done quick tune for mileage and performance. i was wondering does anyone know how to calibrate the dual exhaust with it? or does it even work like that? and also what would be a good custom tune for performance mode and mileage mode? I am very new at all of this and am not sure at what all this flashpaq has to offer.
Thanks a bunch

 

Superchips does not give you a 'custom' tune per se. It's what is called a 'canned' tune. The parameters are set in the program. A custom tune is written for your exact combination and can be updated to reflect mods/changes. Since you have a 2005, you are in a great position for custom tuning, though with just a catback it may not be worth it. Now if you start upgrading major things, like gear change, converter, cam, heads, then a custom tune will allow you to take advantage of all of these things.

 

Yeah custom tunes arent cheap but are the way to go.

Since you got the SC though, you should get the trans tune if you havent already.
