Thermo Master Power CHips include all the features of the Street Runner. It is programmed to use a 160 degree Powerstat. Both of these Power Chips are programmed to recalibrate fuel delivery and ignition timing to deliver maximum torque and horsepower without sacrificing reliability. Power Chips also delays the torque converter lock-up until high gear which improves driveability. Installation is easy quick-just plug in the new Power Chip.
