Hi from Finland.
Have someone here in this forum an: 2015 SEA-DOO GTI SE 155
I am wondering the stop speed of this jet. With my GPS it is 39-40knot.. (is'it about 46mph)

I think it should run little bit faster, or what do think here in forum?

-Mika
 
My Loaded GTX with a 155 hits 50 mph easily and can hit 55 in rare circumstances.

Okey,
My SeaDoo is new... are there some 10h rule here to get all RPM of my Jet?

Read something like this below at internet...
"After the 10 hour service is performed the ignition should be reset as to offer you optimal performance with a top RPM"
 
I have a 2014 ltd gti 155. It runs 59-60 on glass. Yes it will go faster after the 5&10 hour mark

Once you break it in, it will go a tiny bit faster by default. But there's after market intakes, impeller(s), etc. That will get your Seadoo up in a bit of horse power.
 
i wish they had a tune for the 2015 gti 130 to make it a 155. i did the research and it is all in the ecu.

is it true that once the ecu get 5 and 10 hrs it unlocks full power? and is it noticeable?

My GTI SE155 has 20 hours and runs 55-56. It has hit 58 a couple times in right conditions. I also have a 2015 GTR 215 and it runs 65-66 but just tuning 10 hours.

It is not just the ecu. Upgraded injectors and cam as well. Cost is not worth it at all

i cant remember where i read it, it may have been a service manual, but the cam lobe specs are the same 130hp and 155 hp.
it make sense it would be no different than a 60hp spark to a 90 hp spark. just a ecu tune unleashing whats already there.

is that is sport mode?
 
There was a noticeable difference. I think it opened up at 10 hours but now I have 30 so I don't remember exactly. It's a great ski and I love it.
