advanced timing on a gq
i have 1990 modded GQ ute,was non turbo engine sivler top,
its now has a custom turbo ct26 and intercooler,
read a post on here a while ago about advancing the timing and cant seem to find it again,
just wanted to know how much you advance it by with a gauge or by eye are we talking mm in movement,and the advantages in doing this ??
a squirt of diesel sooner??
any help would be good thanks
