How can I see what this motor can put out.

here are the specs...
https://www.cummins.com/engines/isx12-20...n=Overview

- About 475HP and about 1720 trq is about as high as one should ever be set for. It takes a custom program to do that. Of course, the emissions systems will get worked harder than they should too. This means that it would likely have to be de-mandated for it to get there.

Thanks I have came across that spec sheet before. Cummins would only increase it to 425 I figured they could go higher but I guess not. The truck came factory with 4.33s I'm assuming because of the lower hp. I'll just leave it at 425hp till she gives up. Has 600k miles now. I plan to just replace it with a 15L so hate to blow a bunch of money on special tuning. I would rather leave the emissions long as I can as well I have had 0 problems with it the last 100k miles..
Thanks again.
