Spark - What Octane for V-Tech Tune???
Just curious what octane unleaded gasoline guys are running with the V-Tech tune.
I'm curious for the 8350 , the 8500, and the 8900 rpm tunes.
Performance feedback would also be appreciated .

Ive read u need 98 RON for the 100+hp tunes. For us in the states that equals octane rating of 93-94 (R+M)/2 (R+M)/2 (R+M)/2

I think the 94 is fine for the 8350 not sure about the 8500 tune and some people say that you need race gas for the 8900 tune but I don't have that on very good authority. Just curious on what Octanes are best for what tunes ...

I have 402beata tune and use 98 octane in OZ but it will work on 95 as well but not as good

All the tunes are set up for the same fuel rating regardless the rpm ...
From my experience , there is no point going past 8300-8400 rpm as the props max out speed ...
iam running 8600 tune and happy at 54mph , to hit 60mph u will need more hp which the 900ace won't unless turbo or major works done ..
