Agreed 110%. I had the tune first... then Maggie... then AF1. While I don't plan to run my truck at the track any time soon, I am thoroughly thrilled with the overall pep and added performance that these very simple modifications have brought to my gas pedal... it's a TOTALLY DIFFERENT TRUCK.

Dont think...Just do it

 

why think when you can ?

 

 

hmmm I just figured they would calculate any modifications like exhaust, CAI ect. before programming the chip

 

those mods aren't drastic like a power adder. The computer can learn on its own off of those mods.

 

Things that do not matter to your tune:
Exhaust
efans
intake

Things that may need a possible different tune:
underdrive pulleys(for idle speed)
supercharger
tires (to adjust speedo)
