You would get the same performance gain by just sending me the money and letting me gamble it away. Seriously. Off the shelf tunes have a bad reputation for a reason. Very few of them do anything useful.
I'll respectfully disagree. As said above, I had a tuner in my '99 4.0L OHV Ranger and dad had one in his '00 4.0L SOHC Ranger. I can't say how much of a difference it made in the engine performance though it did feel like it had a bit more pep with the tuner installed. Bigger thing for both was improved transmission shift points. The shift improvement alone was worth the price of admission. Granted those were purchased over 15 years ago, so I'm sure the price of admission was lower then.
The one in the F-250 diesel has it running much better, has dyno proven (by users, not the tuner) results, and a very big following for a reason. It's also got other features that are beneficial for the application and an excellent platform for installing custom tunes if ever needed.
I had a 1991 Camaro 3.1 liter and used a performance chip with good results. No problems and definitely increased HP. I'm not looking to spend hundreds of dollars on a tuner if I can get a performance chip for much cheaper and still get good results. I came to this site to buy a performance chip not discuss what the best way to increase HP. I'm going to buy a performance chip if available. I just have to locate one. All have a good night and thanks for everyone's comments,
Far as I know Jim doesn't sell performance chips or tuners and I haven't seen them pop up much in the for sale section. You probably aren't going to have much luck buying one here. Your best chance at getting a used one here is to post a wanted ad in the parts for sale section of the forum. If do that you will probably get a few scammers try to get you to buy one from someone they know offsite, so check out the person's site activity before you trust them. The moderators do a good job of filtering those people out, but some still get through.
Also be forewarned, threads often get off topic or head in a direction you may not have wanted. It just happens when you post something on an open forum, especially with a group as ADD as this one. Things are going along good and SQUIRREL..
