I have only had my Ranger a month or so and over this period i have contacted several people about custom tunes and each had a slightly different price per tune and a different personality. Of the three Don was the only one to contact me back in a timely manor and he seemed the most knowledgeable, I broke down this morning and ordered the 93 tune and shortly after I found an e-mail with the tune attached.
I just got back from the first ride with the new tune which was only about 5-10 miles in town so I can't say a lot for the performance increase yet but the truck does run noticeably smoother and more responsive.
A big thank you to Don for being such a stand up and knowledgeable guy! I would highly recommend him to anyone and I will be purchasing his 87 tune real soon so I can compare the two!
A little info on my truck..
My truck is a 2004 4.0 4x4 extra cab Edge. I have recently replaced all fluids front to rear, replaced three seals that I found leaking shortly after purchase, replaced plugs with Double platinums, new air filter, new fuel filter, and I replaced both the idler and tensioner pulley as a little preventative maintenance.
