Hypertech Power Programmer Iii Lt-4, Lt4 Chevy Corvette, Impala Ss, Etc on 2040-parts.com

The Power Programmer III is an easy to use, plug and play device that allows you to re-tune your vehicle with Hypertech’s proven engine tuning for more horsepower, improved throttle response, and better driveability. Customers who have used their tuning also report increased fuel economy, from 1 to 2 MPG average.

Simply plug the programmer into the diagnostic port under the dash, and follow the instructions on the screen. Selecting the tuning options is as easy as scrolling up and down, and answering Yes and No questions.

Hypertech tuning works great with most bolt-on mods like cold air intakes and cat-back exhausts. The tunes will self adjust for these mods, eliminating the need for expensive custom tunes.

Adjustable Engine Rev Limiter: Raise or lower the maximum engine RPM.

Transmission Shift Firmness: Electronically increase the pressure of the transmission to firm up the gear changes. This eliminates the slip between gear changes, reducing transmission wear, and lowering transmission fluid temperatures.

Adjustable Transmission Shift Points: Raise or lower the maximum engine RPM that the transmission shifts in each gear at wide open throttle, from -500 RPM below to +500 RPM above the factory shift point in 100 RPM increments.

Speedometer Re-calibration: Re-calibrates the speedometer, and corrects the part throttle shift RPM for non-stock tires and rear gears.
