dipstick offered you the appropriate idea. The 2 level variance will carry out fine. These engines timings will be taken over by the major cpu as lengthy as you"re close. If you go also far outside it will certainly cause intake kickback and also backfiring through the throttlebody.I collection mine TDC myself and also it took over after first startup and also purred like a kitten. And that was just utilizing my finger in number 1 spark plug hole to feel for air.
