6nz rpm when upshifting and downshifting?

I'd think 1400 down and 1600 up woukd perform a lot better with that engine

 

Depends on rears and tire size

 

The 6nzs ive run kiked 1400-1600 pretty good, 1250 and under was too slow, 1700+ was just wasting fuel (uphill heavy could be its own thing, my current 6ts with its gearing and trans needs 18-1850 sometimes). I got comfortable with 1350, engine seemed happiest cruising at that rpm, lowest noise, best mpg

 

Fuel shutoff should be 2150, I’ve pulled some heavy stuff with yellow motors and much below 1400 rpm the pyro likes to start going the other way

 

I do about the same usually like to cruise around 1300-1400 shift around 1500. I watch the hell out of the pyro though, she gets hot in a hurry below 1400 or so. But 90% of the time I am cruising right around that. Wind is the game changer fighting a headwind or 3/4 wind and I will keep it in a gear to stay above 1500 to keep the temps down

 

Depends, I usually upshift around 1700. Cruise and pull grades at 1500 and not much below. 3.58 gears and 22.5. I do alot of stop and go and still manage 5.7 mpg
