Try thinner spring .9mm, full carbon.
Venturi always .7mm unless u need extra power
The tricky part is getting a smooth, driveable powerband while not being under or over geared for your track. I've almost got it just need to work with the clutch some more and smaller insert I think. Id like to keep stock gearing.
