I've been looking at a few performance chips for my F150 (hypertech max energy and sct sf3 in particular). I'm obviously looking for the gains that come from the chip but also I want one that'll calibrate the tires. On some sites the hypertech says it does do this and others it doesn't and I've only seen the sf3 not doing the calibration for my particular model.. so my question is which is really true? I'm new to the forum and ford mods in general so I appreciate everyone's input!
