Cummins PCM Upgrade

[CDA]

I did a search and could not find anything, but has anyone flashed their Cummins PCM to get more HP? Saw a guy claim he had Cummins do it and went from 300HP to 360.

I have a Palazzo with the 300HP motor and was wondering if this is an option and what the details would be and cost.

Many folks have done it if they have the correct Allison trans MH3000. The Palazzo doesn’t and the trans can’t handle the 360hp.

BTW, must be done at a Freightliner dealer and folks have paid over 800.00 for it. Very popular on the 2018 Seneca’s with the Allison 3000 but only 340HP

Side note, the trans also limits your towing ability.

That question was asked at the Cummins seminar today and Cummins confirmed the trans can’t handle the up rate. Different rig same issue.
