Single or Dual Plane J Code?

I'd say either is gonna be a big improvement over the 'C' code. I dunno if you'd be able to tell much of a difference between the two 'J' codes though.

One of the off-road mags did a test a number of years ago and there is a difference, not that I can remember which was better :doah:. I'm pretty sure though any difference is only seen on the dyno, would be hard to tell by seat of the pants. Either would be a good improvement over the C code though.
 
what change is made in function between a single plan and dual plan manifold on an engine with no manifold vacuum?

i am a diesel newb trying to learn more.
