Recently I purchased a "machined street cam" from Kent Crowder@ Scheid Diesel for my 04.5.
Scheids it seems is the only company marketing a cam for the 3rd gens at this moment to the best of my knowledge.

Friday it was installed and I picked it up.
First half hour of use, I was instructed to let it idle by Kent.
After that I took it easy and drove it about 14 miles home. The next day I drove it roughly 80 miles and kept the rpm's down and kept the foot light on the pedal.

Today I took it for another spin, about a 3 hour drive down south and back home again.
By now I cant get over how much quieter the truck runs, and the engine runs smoother to boot!
Turbo spool up is even faster than before, and mileage has gone up 2mpg with on highway driving.
4 hours of driving and I used a 1/4 tank of fuel and this is an 04.5!!!!
Im still amazed at the mileage!

I have only romped on it a couple times and it was enough to get it sideways a hair at about 70mph with the TST on level 2x5;ez-3.
Spool is even more instantaneous!

BTW Drone is gone, engine is quieter on the interstate, noise tone has changed some a little deeper but overall quieter.

 

Sounds yummy! Mind if i ask how much? How about labor? I didn't even see it listed on their site. Is this an item more suited for a truck with some mods on it? how about its effects on longevity, hard use? maybe i should call them up but its sunday and i bet others here have similar questions!

As far as mods go, I don't know it would probably be nice in a stock truck too.
