This may be a dumb question, BUT, when setting up a forge split r dv, or in other words turning dial round to the required setting "clicks",

Can this be done with the vac pipe off?

The reason I ask is because if I need to turn several rotations I will struggle with the vac pipe twisting!

Is this a silly question, I don't know lol

Thanks in advance.

Set it up before you fit it (i.e. before you put the vac pipe on)

From memory I think I set mine to something like 15 clicks away from "fully loose" and set the one on my mates car with a remap to 18 clicks away.
