Does any one know if you can use a 94 stock chip in a 93? I was digging threw some of the spare parts i got when i bought my 93 and came across the 94 computer that came from the car that donated its engine for mine. It was an 4r70w car as well so that makes me think that it won't work. The reason i'm asking is cause the previous owner of mine installed a hypertech chip and i now want to remove it but don't have the stock 93 chip. Thanks!
