I have a 2002 F150, 5.4 with towing package. I bought this pu new. I have all the hp I need when pulling my 27 foot TT. Would be nice to get better mpg. Has anyone tried the Hyperteck Power Programmer. If so, does it help. Thanks
You posted this in the wrong section. It should have gone to the 97-03 section. But to answer your question, probably not much. That combo was extremely thirsty and underpowered for some reason. It should help driveability, though.
