Hiya every one.
My dad is buying a new ford 250 PS
And asked me about chips and wants to buy one.
What i'm looking for is the best chips for improving millage?

 

Firstly, you want a tuner, not a chip. Hard chips are out dated and don't offer you much play room, tuners/programmers allow you some tweaks. What works great on one truck will not perform exactly the same on the next, there are Calibration codes that make a bit of difference.

In any event, you can't go wrong with the big names like SCT, Sniper, SuperChips, or Edge products. I am not a big fan of Granatelli, bully dog or Jet, but that is only based off my experiences in sales.
