15/19 3 Blade at 8100?
Who has tried running a 15/19 3 Blade with the stock ECU?
What did you think, numbers would be great?

I have a 15/19 3 blade on my ski and love it. It has a great holeshot and acceleration is awesome. My ski runs 75.5 in 90 deg air and 85 deg water temp @8150. I have just purchased a reduction nozzle and plan on trying the 82mm to get my rpms to 8100.

I lost a solid 2+ mph with the 15/19 at 8100 over the 15/20. I think the average is a 1.5-2mph loss between the two on the stock ECU.

But is the acceleration that much better?
I will have two setups. One with my 15/20 and one with the 15/19.
I use the 15/19 for giving rides mostly and just messing around. Was just looking for more accel!

I put a 15/22 on my ski last weekend and there is a noticable diffrence in acceleration... not off the line but say from 1/3 throttle all the way up. Also you will lose some mph with the 15/19 on the top end.

None. Perfect 8100. I could tell the acceleration was better, but it wasn't enough for me personally to give up the 2 mph.
