Hypertech Power Chips are direct replacements for the stock chips in 1981-1995 GM vehicles. The Power Chip contains the Hypertech Power Tuning data that controls the engine's air/fuel ratio and spark advance. Power Chips can be installed in less than 30 minutes using only hand tools. No wiring or soldering is required - just plug in and go! Street Runner and ThermoMaster chips both contain Hypertech Power Tuning programs. ThermoMasters contain special programming that allows the use of a 160-degree or 180-degree thermostat. If you can't or don't want to change the thermostat, then use the Street Runner.

Street Runner Power Chip

The Street Runner Power Chip is designed for daily street driving or competition in unmodified vehicles using a stock thermostat. The Street Runner Power Chip contains Hypertech's powerful engine tuning information to deliver maximum power at full throttle (with increased boost pressures on turbocharged cars). The Street Runner also raises RPM for torque converter lock-up, producing better drive ability and smoother shifting. Mileage and emissions during ordinary daily driving are not affected. The Street Runner Power Chip puts fun and excitement in your driving and gives you the extra power you need for passing, pulling, or maneuvering out of a tight situation.
