TSuperchips' original products were EPROMs (or "chips") which could be installed in place of the original OEM EPROMs located in your vehicle's on-board control module.

These chips, just like the tuners of today, keep the entire vehicle safety and emissions systems intact, but modify the fuel, spark and transmission settings to deliver dramatic power, torque and drivability improvements. With the advent of OBD-II vehicle control module in the early 1990's, most domestic vehicle manufacturers installed under-dash ports ("ALDL ports") which allowed dealers and service techs to "re-flash" the vehicle's control module to change engine settings without replacing an EPROM.

So today, instead of chips, Superchips primarily sells hand-held tuners which achieve the same dramatic drivetrain improvements, without the hassle of popping the hood, pulling out the vehicle control module and replacing a chip. Installation is quick and easy, taking just 10 minutes and requiring no tools or mechanical skills whatsoever.

Superchips offers a complete line of hand-held tuners to cover most domestic cars and trucks. While we are famous for the incredible power gains (12% increase in HP on gas vehicles, up to 150HP increase on diesels), our engineers and calibrators design the products for drivability. No more downshifting on big hills, we tune throughout the powerband for consistent performance from 500 to 8,000 RPM. In addition, our customers rave about the fuel efficiency gains, even while picking up, on average, 50-60 extra horsepower.
