I have a 100 shot of nitrous and the timing should be retarded anywhere from 2-4. But is this 2-4* from the advanced timing tune, or do I retard it 2-4* from the stock tune? I just bought a diablosport and the timing is in % and it goes all the way up to 40% retarded to 10% advanced. What % should I have it set to for a 100 shot? It also lets you set it in 2 different rpm ranges from 2000-4000 and then 4000-7000.

Thanks

 

anybody know?
