what is the overall best mod for the money to add more power to a 98 5.4 engine? Any suggestions?

 

I'd vote for the Superchip. I have one and it's a nice bang for the buck mod.

Superchip !! I really get a kick out of gear changes as well.

 

i think i got the least performance out of my superchip.......honestly....i like the custom program options but it didnt really help a whole lot. best mod for the money is electric fan/pulleys combo........pulleys are absolutely the best single mod you can do. coupled with a fan, get ready to go a LOT faster down the quarter mile.......more than half a second faster.
