From what I have learned on the VW site, you can make small adjustments to where you want the power band.
My personal opinion, on the A series, I think it is a hell of allot of work to make ajustments. You will probably need to remove the radiator and struggle to see the cam sprocket clearly enough to make precise ajustments. But hey, that's just me.
Bou jou eie branch man. Dis wat ek gaan doen. Ek het 'n kakhuis vol fotos gekry en gaan probeer om 'n pipe bender te leen by iemand. Nie hydrolic nie, maar daardies wat jy met die hand werk om te buig.
Lyk my ons wil dieselfde goed laat doen. Ek gaan 'n cam laat re-profile by Camshaft Dynamics. Dis goedkoper as om billet te koop. En my engine gaan A12 bly met verbeteringe.
