Can I install this Hypertech Street Runner power chip myself or take it to a shop?

Installing the Hypertech 159361 Hypertech Street Runner Power Chips requires opening your vehicle's ECU case and carefully swapping the factory PROM chip with the new programmed one.

Will this Hypertech Street Runner power chip be detectable during dealer service visits?

The Hypertech 159361 Hypertech Street Runner Power Chips is a direct physical replacement for your factory ECU chip and is completely undetectable once the ECU case is closed back up.

This makes it one of the most discreet and stealthy tuning options available for your vehicle today.

Does this Hypertech Street Runner power chip come for both gas and diesel engines?

The Hypertech 159361 Hypertech Street Runner Power Chips is available for both gas and diesel engine applications, but each chip is programmed specifically for one fuel type and cannot be used interchangeably. Hypertech programs each ThermoMaster and Street Runner chip separately based on the vehicle's unique ECU calibration identification number. You must use our fitment lookup tool or contact us with your VIN to receive the correct chip for your engine.

Will this Hypertech Street Runner power chip help improve my fuel economy during daily driving?

Many drivers report gaining 1 to 3 MPG after installing the Hypertech 159361 Hypertech Street Runner Power Chips, especially when driving conservatively on the highway. The optimized timing curves and air-fuel ratios promote more complete combustion, which means less wasted fuel during light throttle cruising conditions. Remember that frequently using full throttle to enjoy the extra power will offset any fuel economy gains you might otherwise achieve.

Will this Hypertech Street Runner power chip work on my stock truck without other mods?

The Hypertech 159361 Hypertech Street Runner Power Chips is specifically designed for stock or near-stock vehicles and works perfectly with all factory engine components and emissions equipment. Hypertech calibrations stay well within safe operating limits for ignition timing, fuel delivery, and all other critical engine parameters. If you plan major modifications like forced induction or camshaft swaps later, a custom dyno tune would be more appropriate than this pre-programmed chip.
