    I have a 89 3/4 ton Suburban 2wd with the 454 and a friend has come across a HyperTech computer chip for a 87 454. My question is will this chip work in my truck? I have a part # and serial # if that information will help. I will not have to pay anything for the chip so I just need to know if it would be worth installing, if it will work?

    Thanks for any help you can give.
