ISX CM870 De-mandate help

Several years ago I had the engine de-mandated using only software and the non-venturi intake. The software and intake came from a shop in southern MN. Since then we have installed a reman engine running with factory equipment. This engine is a 565hp CPL 8518.

We had to replace the oil coolers so we had the EGR cooler off the engine. One of the connections to the block has been leaking and I'd rather just not put it back on. At this point I'm not sure whether to do a "Stage 1" or "Stage 2" de-mandate. I still have the {name removed} and tune but the shop in southern MN will not even acknowledge there existence. Is there anyone here that could take a look at the files on this {name removed} I can trust and maybe adjust them if I need? I'm not sure if it will work properly by taking the tune that was once on a 500hp engine and simply installing it on a 565? If I remember right there were two tunes for options. A 5% economy tune and a 12% HP/Economy tune.

Thanks for your thoughts.

You made it to Rawze.com -- This place is where bulls#it and bad engine life-span sucking, over-priced, over-hyped, faith-healing junk-tackery, ego-boosting, false half-arssed garbage-bin tuning, boxes, etc. and bulls#it engine-hacking crap / stupid redneck-pickup, ego-stroking truck mods are actually shunned away and frowned upon very quickly.

Sorry, but My site is about actually making your equipment work in ways that DO NOT shorten its lifespan by 80% because of some ignorant fools-gold.

As Nilao suggested, It being a CM870, I would suggest you get with Mommaburt or Unilevers and educate yourself in how an engine should be properly cared for and should run without all the ego-boosting hackery crap you have been brain-washed with before you got here. Most if not 99% of everything you mentioned is not worth putting onto a lawn-mower nonetheless a commercial engine.


As soon as you mentioned those garbage words "Stasge 1,2,X" -- complete horse-s$it, I know there will be about 200 people on this forum shake their heads in sadness at yet another brainwashed victim of those kinds of ways of backward thinking.

Maybe you should also read through this kind of stuff while your waiting for a reply ...
