Catalyst Gets a Tune by Thunder Products Clutching!

Thunder Products Clutching has more seat time on the Arctic Cat Catalyst more than anyone else. But, they don't only offer clutching improvements, they've also developed a fuel mapping that vastly improves the factory tune. I talked to Terry about this at Hay Days and learned a lot, not only about the Catalyst in general, but how they can help the sled run at its best - and extend engine life.

There are 2 ways to get a tune: 1-Send the ECU to someone to transfer the data, or 2-buy a tuner that you plug in yourself. I opted to send the ECU to Thunder Products and in this video, I'll show you how to remove it and reinstall it once you get it back. The process is a lot easier than many people would expect and can be done with only a socket set and T-27 Torx bit.
