Who makes best chip for 03 Ranger 4.0 Auto

Diablo, Jet, or other? What luck have you had with your power chip?

More important than the chip manufacturer is the person flashing it (and their knowledge/resources). Motorhaven right here is a great place to buy from (I have a Diablo chip from them that I've been very happy with).

I love my Diablo. You can get it off of motorhaven.com, just click on the words "Parts Shop" in the upper right hand corner of the screen. Expect 8-10%HP and 10-15% torque gains. or 17-21 HP and 24-36 ft-lbs. Stay away from jet and hypertech as they only tune at full throttle. Diablo will tune for all throttle positons and makes a real noticeable improvement in all around driveability as well as max performance. I don't know much about the Aptn chip, probably similar to Diablo, but I bought from motorhaven because Ken (webmaster of FTE) owns it and he makes this site possible.
