i have read about some of you talking about wheatley tuning-- is it all that you make of it- or would a hypertech programer be better- i mean at least it gives you a code scan for your money??? Also, i have a k&n intake, gibson headers, dual flows, iridium plugs, oversized wires. anything else i should look into before chipping it???

 

From what i have read a custom tune is the way to go only $275 and they will update it for free and your truck has no down time because they send you a core and you send them your back.

 

Get a 160 degree thermostat and a custom tune... As far as code readings, Auto Zone does it for free... Can't beat that...
