lol i know only 14psi and whistle like a locomotive but i think i need a boost fooler.

 

4-6psi cruising. 55psi WOT - II SPS66 with everything turned up.

 

i am pretty close to that as well, i am at 4 to 5 at 70mph and at WOT i was at 56psi but was pretty toasty so i turned it down to 49 to try and help out a little.

 

6-8psi @ 75mph.
32-34psi @ WOT.

Just cruising(70) anywhere from 8-12 psi. WOT goes to about 44 psi.

It's looking like the short beds run less boost? Am I seeing that correctly?

 

Lighter truck=less boost when everything else is equal

Also, aerodynamics has a LOT more to do with cruising with these trucks than most people think...when I put the flatbed on 95 95, I lost a solid 3mpg highway!

That being said...on the 95, cruise is between 6-12psi, wot is about 36psi!
On the 98, cruise is 4-10psi at 70, and WOT is 41psi...when the tranny holds!

I wondered how much my bed affected my aerodynamics. I've been wanting to get hold of some smooth metal plates and a welder and see if I can help my towing mileage and it might help my empty mileage too.
