What were the weather conditions and RPM were you went 77. I will assume you are getting your speed from the dash.
What were the weather conditions today?

Obviously you need to move north. All the Sea Doos in NY are 4 or 5 mph faster!
I hit 53 on my 3UP Spark, 58 degree day.

Sounds like too much speed loss just due to heat

Your ski (all skis) suffer a 5% +/- loss of horsepower between spring/summer. Factors are: Air temp, altitude, air pressure, humidity. Other factors (that you control) are fuel weight/rider weight, and maintenance items. A quick check using an engine power calculator showed your ski making 101 percent power in cool dry air vs 96% engine power in warmer/moist air. This is why your ski lost rpm, and it would have lost more rpm without a scom. The same will be true with a reflashed ECU.
