What Parameters Should I Change?

At HP Tuners, we make software and hardware tools for the best tuners in the industry. We can tell you how to use those tools. But, learning how to tune is something you really need to go to the tuners themselves for. Fortunately, there are a lot of good resources out there:

Our forum contains a lot of information posted by our customers over the years.
Our YouTube channel has a number of great tutorials. There are also a number of tuners who have posted some great content on their own channels.
Training courses on how to tune with our software are offered by a number of third parties.
There are some good books on the fundamentals of tuning out there.
