Spark V Tech tune and re pitch

[SLASHER]

If your are looking at a tune , then grab a V Tech but highly recommend re pitching prop to gain max Speed ..

I am using the 402 8600 tune and removed 4mm of the trailing edge which gave me a 400rpm gain ..

Hey Slasher, I am at 7600 rpm and 43 mph with 90 hp spark. I am also at 8000 feet of elevation. I need decrease my pitch by 4mm in order to get to 8000 rpm's, correct? Basically what you did just to get to stock rpm's.

Repitch prop and seeing 8400 at 52+mph

Yours sounds like 60hp

He's dealing with high altitude. As the water warms up, I will be also. It is amazing how much altitude sucks power.
