FS Hypertech ThermoMaster Computer Chip 91

I am selling a Hypertech computer chip for a 1991 s10/s15 4.3L with automatic. Get more horsepower and torque with lower running temperatures with this Thermomaster computerchip from Hypertech. I noticed an increase in seat of the pants torque and faster acceleration with the chip installed.
