Ok I am about to get a 05 Mack day cab for my new work truck. This is a company owned truck but is assigned solely to me. The guys that are coming out of the older trucks and getting upgraded are switching back to thier old frieghtliners because they say the power in these new Macks are terrible. These new ones are really nice and I want to make mine work for me so I am trying to find out if there is a way to turn up the power on it. I am wanting to know if there is something like a plug in fuel box that will work like the one on my 04 ram.. Anyone know where I can research some of this on the web, I currently don't even know what exact engine is in the truck it's got a 10spd (splitter), and I have heard numbers around 330 hp but can't verify... The truck is a Vision series.
Thanks in advance,
Asher

 

Its going to be electronic, which means you'll need the computer to adjust anything. Try these guys http://www.dieselinjection.net/frames.html Nothing on the site about Mack engines yet, but he may have something in the works. Good luck.

 

Need more details. Sorry, I went back and read the full post. It probably has a 330/380 hp program in it. I bet if you drive it hard it will do what you want it to. I have heard nothing but good things on that engine from drivers and the ones I have driven are great pullers. The Variable Geometry Turbo keeps them ready to pull as soon as you hhit the pedal. I think you will be pleased with it. Try it and see. If not, the only thing you can do is have a higher HP program installed from a Mack dealer. You can go up to a 380/410 without changing injectors and turbo I think.

 

If the dealer will do it , they can turn it up in the ECM.
