try launching at about 2500 so it can flash some before you take off that might help ya to get thing scootin off the line.

 

havent tried launching from idle, but i assume it'll be harder on the rear end, i can already feel some heavy vibrations upon launching since adding the higher stall, not sure if it's just cause im making way more power and the rear end isnt liking it or if it is normal, but definatly feels diffrent
