Re: engine knock with ultimate

0.032 spark plug gap is fine assuming you have the correct heat range range spark plug. usually a tighter gap is needed for alky.

Yes a fuel pump is at this point in time as is a fuel pressure regulator.

I set the gap @ .026 on the IX 6 NGK with a MSD-6A. How did it work out for you ?

Re: engine knock with ultimate

so befor I get the new reg and the pump would I be safe lets say running 17 or 18 psi?? or should i just leave the ultimate at the lowest setting?

As I stated ealier,hard pressed to supply enough fuel going above 14 PSI, so meaning, no, do not go above 14 psi.
Leave the ultimate chip in valet mode., Since you are still contemplating going above 14psi.:2cents:
