x15 emissions/ tuning help

[Rawze]

An ISX is a $40,000+ commercial engine ... and "Aint' no hot-rod".

It is also FAR TOO EXPENSIVE to rebuild every few years ... so if you want to go faster up the hills, I would suggest you buy an expensive race car and tear it up instead. It is far cheaper to rebuild a car engine to have fun with than torturing an expensive commercial engine/truck that is supposed to turn a profit.

Your on the wrong forum if you want any of those super-trucker idiots telling you otherwise.

===============

First of all, I do not encourage (nor discourage) people to de-mandate their stuffs. If they want to keep those systems maintained and operating it going properly, then here is more info on this: https://rawze.com/forums/showthread.php?...2#pid73072

However, I do not blame people for doing such things, that is their decision to make on their own. ,... This, assuming they live in a country that allows for it.

That being said ...

As far as de-mandating it goes, there is a place around about every corner to shove some file in there to make codes disappear. But in return, you get an engine that lives a very short life most of the time as a result.. because most of them are clueless, yet all claiming they are the best. Your chances are better going down to the worst red-light district known, and then wondering why you ended up with an STD that cannot be cured.

I.E.> it can be done right,.. but its damn near impossible to find someone that can ... and the more 'well known' someone or some place is, this should actually be the 'least trusted' with regards to that type of stuffs.

Maybe you should read thru this article instead...
