Between the combination of a cam and head porting, I also noticed a drastic drop in drive and boost pressure at a given load and RPM.... When the truck was in pretty much stock form it took about 15 PSI boost to maintain 65mph on level ground, after the improved head flow it dropped down to about 6-8 psi.. Mileage improved especially at highway speeds as well

To overfill the NV4500, I used a piece of rubber hose that fit snugly in the filler hole and filled it with a funnel from near the turbo... once filled, I quickly pulled the hose out and put the plug in. I want to put a temp sensor on my tranny, but won't be doing that until I do the NV5600 swap and 3.55 gears
