custom tunes are the way to go, and id recommend the gryphon for custom tunes. I have never heard a negative review from anyone on here about php. also i think you should really look into getting a leveling kit. gives your truck a much better stance and more ground clearance offroad. i have had one on my truck for about 50,000 miles and have offraoded mine pretty hard and have never had a problem due to the leveling kit.

 

Okay, PHP gryphon and Monroe Lift struts. What else? Theres like 300 left, roughly.

 

Flareside,

Does she already have a K&N air filter? I have a 2008 DSG STX with the 4.6L and after a K&N filter, Gotts mod, and a single Original 40 SIDO Flowmaster (3" pipe/4" tips) exhaust on my truck, it seems to have opened that little 4.6's eyes. One question for anyone--what is the purpose/advantages of underdrive pulleys? Heard them discussed on the boards but not sure it is something that would benefit my truck or if it would be wasted cash...
