Last Sunday was the first race of the year. It was a longer 8 mile loop with a little bit of everything. Mud holes, logs, super tight woods, very deep sand. My bike performed perfectly the entire race without any issues. In the deep sand there was a long uphill that took lots of throttle and my bike pulled hard all the way up the hill, never even hit the Rev limiter. The bike feels like it wants to pull forever. It's like it's a whole new bike. I'm absolutely a believer in your tuning service and will recommend it to anyone I talk to. I'm extremely happy with its performance and your tuning. Thank you!
