Probably one of the hardest systems to learn to use , not alot of support for it , most guys are going to Moates or Tweecer stuff for self tuning , cheap , easy to use once you figure out the basics ....if you wanna know more about that system though if you search FORD EPEC , you will probably find more information than just searching the part numbers
what are you going to tune ? foxbody , 94-95 ? Special Forces for Sniper only works on 96-up stuff that you flash ....but they do have a setup (Commando) like the SCT PRP for alot less money that comes with chip and chip burner , im selling them from now till Jan31st for $639 shipped
