Does Dyno-tab® reduce emissions and, if so, do you guarantee that my 1990 Honda will pass the California emissions test if I use it?
Yes, Dyno-tab® reduces emissions in most cars, but the reduction levels depend on the condition of the car to begin with and the fuel used. Many customers do use Dyno-tab® prior to getting a smog test, and we have very strong test data to support the claim of reduced emissions. But, no, we do not guarantee your car will pass the test. There are many factors that can influence the outcome.
