    Hey,
    Ive got an 89 Jimmy (fuel Injected). I recently installed a Hypertech THERMOMASTER chip. My question is this: Has any one else put this chip in their truck, and what temp. thermostat did you use? I changed my thermostat, but my truck has been getting hot lately. It might be something completely different than my thermostat, but I want to check and see if I put the right one in anyway. Any other suggestions would also be helpful. Thanks

    I think that you are supposed to put in a 160deg. thermo in that application.

    I'm thinking of a thermomaster chip for my truck. Did you feel a power difference. Any change in mileage? Are you satisfied that the chip is worth the money?
    Thanks
