A lot of this depends on a number of factors. We perform all of our tuning and testing in-house to verify that air-fuel ratios are safe and will not cause damage. Possibly the most important factor is to verify that the engine does not run lean in any part of the engine’s RPM range. Our recommendation is that if you have a tuner or a flash on your machine consult with HMF Tech team as well as the technical support for your particular tune/flash.
