Does Hypertech Power Tuning work with modified vehicles?
Hypertech Power Tuning is calibrated for stock or near-stock engines (engines equipped with high-flow air filters and cat-back exhaust systems). Any additional modifications that alter the engine’s airflow and volumetric efficiency, such as installing a modified mass airflow sensor, high-lift or long-duration camshaft,ported heads, headers, supercharger, nitrous oxide, etc., would require new tuning. This tuning must be done individually on a dynamometer with a vehicle equipped with those parts. If you have modified your engine with aftermarket equipment other than a low-restriction air filter or cat-back exhaust, the Power Tuning developed for a stock engine may not be correct. Note that Hypertech Power Programmer III provides many additional benefits beyond Power Tuning. Depending on the application, you can adjust the engine’s rev limiter, raise the top speed limiter to match the speed rating of factory-approved tires, adjust the transmission shift points and shift firmness, correct
