    I have a 2012 ultra 300 with solas 14/21 being only mod. my boost guage goes up to top then settles back down to around 13. is this normal or is the wastgate opening too soon? Thanks for any help.

    How many rpms you turning?
    You don't have the ski delimited so you should see 7500-7600rpms @67-68 mph..
    If not could be a boost leak on one of the many Hoses,make sure the clamps are all good and tight..

    My ski would shoot up to 16 lbs then drop back to 8-10 lbs until I found the leaks , then problem solved

    My 300 had the same set up a while ago just the 14/21 without SCOM and flat out from idle it would reach around 16lbs then settle down to around 14lbs.
    Seems normal to me..
