454 mods megasquirt, mpg meter?
I have the same Pathfinder as 5bikes. Learned the hard way not to advance the timing on a 454. Now have hypertectic pistons, Thorley double Y headers. Went from 4.5 to 6.5 mpg. Got to beat that. Anybody tried Megasquirt? Also need an accurate real time way to check fuel flow (usage) on a carb.
