Need Opinions. Have nothing to compare to.
your running it so retarted (timing wise..lol)
I don't get what your meaning is.
Unless you floor it from idle and 20*of V-can timing drops out leaving you with zero, lol. Which is exactly why I speak against running full-time vacuum to the can.... but nobody I know nails first gear with a 4-speed from idle,lol. It's just about impossible.
But usually when running full-time Vcan, your base timing will still be set to around 14/16, with maybe 10 in the can
And yes I agree the Vcan should be hooked up to the sparkport, and not considered in any power timing measurements.
Furthermore, the higher the cylinder pressure is, the more powerful the individual power pulses will be, and that leads to a bucking bronco situation at very low MPH with the timing jumping around as the rpm pulses back and forth on the curve. For this reason, with a manual trans, I fix the idle-timing waaay lower than with an automatic (fluid-coupling), and delay the onset of advance to at least 1000 rpm. Now you don't have to toe the clutch so bad under ~8 mph to avert the bucking.With a stick and a 2.66low and 3.55s, you gotta be sharp down there.
Whereas those automatic guys,in comparison, can get away with a pretty sloppy low-rpm timing tune.
