Couple newbie questions...

[Chamberpains]

Keeping your boost under 20 or at the lowest possible psi is not completely about fuel mileage. Its all about not abusing the most expensive and important piece on the truck. The harder you push that engine, the faster it wears out. Also the harder you push that engine, the harder everything else is working which in turn wears them out faster.

So yes, you get a benefit of fuel mileage with keeping it under 20 or less but the biggest savings in not having to repair or take the time to repair all the other things you abused when you decide to push your equipment to its limits. There is only lost profits in trying to win the race up the hill. Trucking for profit is not about winning any speed races. Its ALL about keeping as much money by the end of the move. And not beating your equipment up will always pay WAY more.

As for the bunk you'll have to check with the dealership and maybe find another truck (maybe pictures online if you can't physically get in to one) and see what all you need. There are slight differences with each model and some are custom built depending on what you want done.


As far as the EGR tune-up... https://quickserve.cummins.com/info/index.html
Sign up for free (register the ESN off the valve cover of your engine) and study the parts that are involved on you particular engine. Your system is setup differently than the 1 in Rawze video but basically the same concept.. EGR = soot return to engine. EGR tune up = pulling EGR system apart periodically and cleaning and replacing sooted up parts in the EGR system.

Also quickserve has everything you can ever want on your exact engine and how to repair/replace everything that has to do with the engine. If you run in to questions on specifics of doing something stop on in here and ask us.
