Hi Douga49,
You can quickly & easily do a search here on the message boards, they have a wonderful search feature, and you will quickly find when you do that few people here use Jet's powertrain programming products due to little to no power gain. That has been commented on many times here on F-150 Online.
Jet, like Hypertech & most other chipmakers, gives you a generic program compromised to run on all similar vehicles, and that tunes the engine for more power only during open loop operation, which is only when you are at extremely heavy to wide open throttle. The rest of the time there is no power gain, and that type of product yields poor results. They do it like that because it's much easier and cheaper, and most people don't know the difference until they've actually used a good product like the Superchip to have a good comparison on the same vehicle.
By all means, take your time and do your homework, if you'll use the search feature you can find that kind of info and read what their users have to say. In particular, look at posts where people have used both the Jet chip and the Superchip on the same vehicle.
Good luck!

douga49,
Back in 97 I installed a Jet Chip on my truck. The truck ran fine. Then when Mike told me Superchips finally had a chip for my powertrain, 97 4x4 4.6 w/5spd, I ordered one from him. It made the Jet chip look like the stock program. Well I kept the Jet Chip, couldn't sell it anyways. When I picked up my 00, same powertrain configuration, the first thing I did when I got home was to call Mike and order a new Superchips. Just for fun I tried the Jet Chip and my truck started and ran. The PCM codes for both trucks were totally different. The 00 has COP and the 97 didn't. I suspect they use generic programming and don't tune for individual PCM configurations. FYI the 2000 and 2001 Jet chip for the 4.6 auto F-150 has the same PN.

Well said, JMC.
Jet's programming is indeed "generic," just like Hypertech & almost all other chips, one of a number of reasons why they do very little in these vehicles.
The Superchip is the only one that tunes each vehicle according to it's code, tunes at all throttle positions so it adds power under all situations, and is still 50-state emissions certified.

Not trying to stir the pot, but a couple of corrections here.....
Jet does make a chip that tunes at all RPMs, but it is not a CARB approved chip and is sold for off road use only.
As for the codes being "generic" this is a matter of opinion. Though the chips may work in several vehicles, this does not mean the end code is the same. Having seen dumps of a couple Jet chips for both a standard and auto 5.0 'Stang, the timing tables varied considerably and it is apparent the programs were intended for different applications.
The end code is really all that matters. The biggest advantage to tuning per code is for the manufacturer in most cases. This allows them to keep the chips from being pirated and used with other calibrations and limits resale to the same calibration vehicle. Protecting their product is only smart business.
As with any product, it's not rare to see positive and negative about any given product. Overall I haven't heard much positive about the Jet units, but PKRWUD was pleased with his improvements in his 4.9, and I suspect he had the Stage II chip.
As I said this isn't intended as a knock. Considering chips the Superchip would most likely be my first choice. I really have to do something about this crappy shifting...
