Default Gryphon Custom Tunes question...
I have a '06 F150 SCREW 5.4 2WD 4:10 LSD, Magnaflow S-Exit Ctbk, AFE Intake Tube only, LPD Trans Coolers, Gryphon Custom Tunes & I've enjoyed this set up from Bill for over 2 years now. I want to get Long Tube High Flow Cat Headers from Dynatech and wanna know if another custom tune is required to run those or can I run the tunes I have?

According to Dynatech, a stock F150 with their Header/Cat combo doesn't require any special tune.
