Peter Harrell at Harrell Engine and Dyno has been tuning Cleetus McFarland’s race cars for the last couple of years and has made some big advancements in his racing and engine programs. He’s been at a lot of races with the team, and has tuned them to several wins, but he also tunes for a lot of other people at a lot of different races and can’t always be there on site for Cleetus. Luckily, it’s 2025 and it has never been easier to remotely tune a stand alone EFI system. In fact there are a lot of tuners who never actually touch the cars they tune, because they do most of the tuning remotely. If you have wondered what that process is like, you’ll love this video because that is exactly the topic.
