Considering boosting my 330 Cummings

Just bought a 2004 monaco diplomat with a 330 cummings. It seems a little weak for power. I was told you could boost the power with a computer adjustment. Is this true and what should I have it turned to. Is this a good idea.

If rear radiator ISC 8.3, check out fan kit from Source Engineering. Might be all you need.

Best,

Check out "results of straight pipe installation" in the cummins powertrain section for a very simple and inexpensive means of more power and better performance

Also the MP8 can be installed. One rotary knob and you can up the no and torque 15%. I have had one on a Cat for 25000 miles and added a few gauges to see all is well. Do a search on t h e NP8 and get all kinds of info.

When/if you search for add-ons for your rig, be sure to spell your engine make: Cummins, not Cummings. You will most likely get more search results.
Named after Clessie CUMMINS

The limiting factor is the Allison transmission torque limit. http://www.allisontransmissionpublic...d.ashx?did=740
Down about 2/3 of this pdf you'll find transmission specs.

Had mine reprogrammed from 330 to 350 and definitely noticed a performance change. It will climb hills better now thanks to an additional 100 lbs of torque and the fuel mileage has improved 1/2 to 1 mpg. Just make sure you give the Cummins place your engine CPL (critical parts list) to make sure you don't over stress your drivetrain. Wished I had done it years ago. Good luck!

Mr. Hipster
CAUTION!
Simple Green® Original/All-Purpose is NOT safe, or recommended by the manufacturer, for cleaning aluminum.
Simple Green® Extreme
is the recommended product.
