You cannot adjust the amount of advance in the can. Only the "when" you get the advance. I've told you multiple times now. This is combo dependent. ******* TRY IT AND SEE.
Ah, but you can.
Pull the advance canister, the number stamped on the arm is the advance. Either add material to the notch (weld or JB weld) or file the notch to limit or extend the pull length of the canister, if you don't feel like swapping canisters and stocking a hundred canisters for tuning.
