I have a 2003 F150 Harley with 10K miles. I am looking at both the Superchips MaxMicro which offers a HP tune with no mods or a second HP4 tune if you change out the pulley. Diablo seems to offer a bit more versatility for the same bucks. I was wondering if anyone has had experience with either of these units and can make a recomendation? Which would you buy? I eventually plan to put an exhaust and cold air intake but in general it will remain stock. Thanks for any input.

 

I've used both at one point or another. Between the two, Diablo is hands down the better programmer. It's got a ton more features and options for future modding or for just staying as you are.
