Had my first ride on my mcx nytro was skeptical about 4strokes for years but always curious . Absolutely loved it these sleds are just sick. Never had to worry about flipping over backwards while climbing hills before . Can't wait to see what this thing will do with the skies planted and a good track . Just one thing my boost gauge would spike to 17lbs then drop back to 14lbs is this normal . I want to get a boost controller has anyone tried a e-Boost2 controller from turbo smart. First boosted sled so any help or suggestions would be appreciated thanks.
