Silly little baffles, LOL!
Well, you'll need something to regain some of the low-end torque you lost by installing FartMasters --> https://www.f150online.com/forums/sh...little+baffles
Having said that, tuning is generally not required for any after-cat exhaust mods.
With the 3" version of the AF1, you'll be fine - anything else, you may need tuning to correct for MAF TF changes.
Recommend getting familiar with the Search function - it's great
