Power Boost chip for 300 HP Cummins

If your your 2001 is an electronic ISC (8.3 liter?) with an Allison MD3000 trans, which is likely I think, then cummins themselves can and will (for a fee) boost it for you. A factory cummins tune uses torque management to limit max torque to 1050 ft-lbs, and to reduce torque briefly during the shifts to keep your trans happy.

Call your local cummins dealer service center for info.
I haven't actually gotten it done (mine was still under warrantee when I discussed it at nPower in Hodgekins, IL) and the service guy said it would void the warrantee and I should wait. He said he could get 400 HP out of my 2008.

passin thru: You have omitted the fact that not all Allison's are the same. A MH could have a 2000, 3000 or 4000. All have different ratings for Max. torque and the GVW of the coach, The unit in an 80,000 lb. truck is very different. Your years as a mechanic should have made this obvious????

John Wayne, I'd like to see proof of that statement because they use the same Allison in heavy trucks pulling 80,000 lb. With a MH you are only pulling around 50K so it equates to the same thing. IF i can floor a 500 HP Detroit with an Allison I can floor a MH with a 500 HP engine or did I not interpolate correctly? OH, wait, I only have 30 years as a Master Mechanic so I probably don't know what I'm talking about.If you turn a Cummins 330 HP to 400 HP you go up from 900 for 1200 ft lb torque and that is not enough to tear one up for a million miles. Call Pittsburgh Power and ask them.

The engine can take the boost BUT the trans can't take the extra torque. So you will go better till the trans gives up.

Look into the Banks Power Pak. We also have a 2001 K-Star, same engine and the Banks system made a very significant difference when installed.

Aint no chips for ISC and ISB engines.... You need the computer re-programmed is all
