Thinking of changing exhaust

[RevoErick]

I have a 2008 F150 Crew 4x4 with the 87P & 87T custom tunes. They were written with the truck having a true dual exhaust. The current mufflers are side by side and are going bad. I was thinking of going with a dual in dual out flowmaster muffler. Will this affect my tunes or will I need to adjust anything on the setpoints? Thanks.

I don't remember exactly but I don't think you will. I left a message for Cody, hopefully he can chime in.

Cody just told me that you don't need an adjustment. :thumbs up yellow:
