Gryphon Custom Tunes question...

[GQrider]

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.

You are right on that.

But recalibrating your custom tunes to accomodate for them soil be an extra added benifit.

Also make sure to have new front o2 sensors installed.
