Tuner Resources

Tuning for maximum performance used to be the exclusive domain of experts with dynos. While there is no substitute for knowledge and experience, a new wave of digital tuning tools are making it possible to precisely tune any engine without long and expensive dyno sessions. The key is to measure and record the critical metrics- air/fuel ratio, cylinder head temperature, injector duty cycle, etc., make one change at time, and then repeat the process.

Whether you’re tuning a large-displacement muscle car, a forced-induction sport car, or a drag-racing snowmobile, the concepts are the same. Here are the resources available on this site:
