I have a 97 f150 with a 4.6l, and I was thinking of getting a tuner with both a economy mode and a performance mode. I have heard the gryphon is a good one. I have also heard good things about the super chip, but unfortunately they don't make one for my truck. What would you guys recommend? Is it worth it, any downsides, is it harder on my rig?
