I just got the programmer from my brother today (he sold his 2002 FX4) and he reset the truck to stock so the programmer is not VIN locked. The ??? I have, because my brother used 94 octane and I want to use the 87 $$$$, is what are the optimum settings to do for the auto tranny. Offers many different shift points, firmness, etc..I have a K&N intake and a 3" catback flowmaster 50 series on my truck (2003 FX4 5.4l.) I don't really have the time to play around with it too much so any ideas would be great.
