slant timing with turbo

it would take some experimenting. 20 initial seams like a lot (dident slants come with 15btdc "stock") and if the limiter is off marking if i set my initial to 15 and the smallest limiter on the plate is 10 and that is not acuret that would put me over 25?
Oh hell no. Some came 0 initial. I think they actually ranged from -2 to 5 or 6. It would put you over 25 if you gave it 20 initial, but a turbo engine will not want 20 I don't believe. Mine does because the camshaft has so much duration. 250@ .050
