Power Tuning is a procedure that Hypertech invented and developed to improve the performance and efficiency of computer-controlled vehicles. An internal combustion engine needs air, fuel, and spark, the familiar "Combustion Triangle". Hypertech Power Tuning optimizes these three elements to produce maximum performance. An engine's power output is directly proportional to the amount of air and fuel that it can burn. Hypertech Power Tuning maximizes engine performance by burning the air/fuel mixture as efficiently as possible, thereby extracting maximum power. Power Tuning replaces the stock calibrations in the on board computers used in late-model cars and trucks. These complex programs control important engine functions such as spark timing and fuel delivery. The only way to modify fuel delivery and spark timing to increase power is to optimize the tuning information supplied to the computer. This is exactly what Hypertech Power Tuning does.
