The Sniper Tuner Special Forces works great, it comes with software you load onto your PC and you make your own tunes. You then load them to the Sniper interface through the USB port and then through the OBD2 port. The special forces comes with 2 bullets meaning you can tune 2 cars with it. It works with any Ford OBD2 vehicles. If you want to buy another bullet to tune another vehicle it is very competitively priced. The cars run great with the sniper tune and I can make different programs for race, street, economy etc. You can make as many tunes as you want for each vehicle. The only thing that I haven't been able to solve yet is the anti theft light blinks non stop after I load the performance tune on my 98, no problems like that on the 96. Even if I turn PATS off it still does it? When I go back to stock tune it stops blinking. Also, I found out the 98 PCM holds twice the amount of memory the 96 PCM does even though they are both OBD2. The Special Forces also comes with datalogging software built in. You plug your laptop to the OBD2 port and it records the data. I haven't had a chance to do this yet as ive been playing around with the paramenters for my performance tunes.
