2019 Skidoo Summit SP 165x3 with Silber Turbo. 1566 miles. The first 500 miles were run stock for break in. Runs great and have had no issues. ECM is flashed by Silber so no need for controller. Have always ran 5 lbs of boost. Also have 3 lb and 7 lb springs. Added side panel vents to reduce heat. PM me if interested or have any questions.
