This is a slightly used Cortex 1950 by Superchips. This unit cost over $400 1yr ago. With this programmer, I made almost 100hp more on my 2008 Super duty diesel. You can remove your speed limiter, improve gas mileage, increase horsepower and torque, adjust shifts points, and you can even log performance information. This unit is upgradeable via online with the provided cable. You can connect to the internet and update your tuner for the latest software. This works with 1999-2010 Ford F-150, F-250, F-350 (Gas or Diesel), 2005-up Ford Mustang V6, GT, GT500, and others...just check out their website at www.superchips.com for more info on it. This is an unlocked unit that you can use on only one vehicle, however, you can order an additional vehicle through superchips update and program 2 vehicles. This is a great buy and a large savings from buying a new unit. You will not be disappointed.
$275 shipped with insurance

 

couldnt find the answer to this, will it work on my 2001 F250 crewcab 4x4 5.4 litre??? been looking for one without success! show me a link that shows what it will do on MY truck!

 

Yes it will...go to superchips.com and do a search by vehicle. It will list the cortex 1950 as the best option of 3 units available.
Thanks
