    Thanks, i had one of the tuners from Dynojet look at this files and he said there is not enough fueling at the higher boost levels. He notice some thing with the TPS that didnt make sense.

    ya that log has problems
    it says you went from 2000+ to 8000+ in .25 seconds
    and you had higher boost at 2000 than 8000.....lol
    that log is missing lots of time
    and that log is garbage
    I bet you got a/some loose connections

    Sorry but these logs dont make any sense.
    Something is wrong with your logger.

    Do you have anyone you know who have a vtech BRP datalogger? if so then you could autotune you ski in seconds. you can get one here

    No i dont, the problem is only when i snap the throttle! If i rev up slowly it runs fine with good AFR!!

    Is there a raw data log on this ski with this bog? The guys that can help need data. The description like "bog" just leads us to where we look for issues.
