What would be the best programmer for a stock 2009 F150, 4.6 2V, 3.73 gear, automatic transmisssion, towing package. Towing a bumper pull travel trailer, approx. 5200 lbs.
Will be keeping the truck stock.
Looking for more hp and torque.

 

I think Edge and Gryphon were getting close to having their programs out. I would go with the Gryphon and the custom tunes. Been running them for 1000s of miles and very satisfied.
