I got an 05 f150 xlt ext cab 4x4 with a newly rebuilt 5.4 motor and a newly rebuilt tranny its all stock right now but I plan on getting aftermarket parts but ive been looking for a good tuner for it iso I have it when its needed ve heard the edge tuner most common for these trucks arent that great and the same for bullydog gt. I hear sct is good nut im not sure which one anyway you guys input would be greatly appreciated thanks in advance

 

Well you need custom tunes for the 5.4, talk to Mike at 5 star tuning. He is active on these forums or go to his website.
