Default 1994 speedo correction

I am changing my rear ratio from 2.59 to 3.75 and need the speedo correction. I spoke to Hypertech and they said that they do not make them. They would have to customize one. I spoke to Jet performance and they said the same. They have one for 1996 and newer and for chips for the older ones but not 1994 and 1995. Are these guys ******* or am I missing something?

I think hypertech means that they don't have it for the exact ratio of 3:75. I changed mine from 2:59's to 3:73's and I was able to use the hypertech III to reprogram mine. If I remember correctly the closest you can set it is for 3:70's. It should only be a mile or 2 off if you use it for the 3:75's but you can even it out adjusting the tire height.

btw. Don't drive it without reprogramming it. I fried my tranny doing that. :U

Get TunerCat and a cable and reprogram it yourself for a lot less than a Hypertech.
