I've got the 94 EFI 4.9 inline 6 and was wondering if there were any chips other than the one made by Jet and or perhaps a computer tuner of some sort?

 

Hi Texas.

Your vehicle would have to be an OBD-II vehicle to use a flash device (hand-held tuner), which didn't start until the 1996 model year. So your truck doesn't have the required OBD-II port where a tuner would connect to.

However, that's not a problem, as we can still easily provide you with a chip that will help out that truck, and do a much better job than the Jet unit, no problem!

Just give us a quick call at our number listed below & we'll be happy to help you with that.
