ISX cm2250 emissions help needed

[T680]

Not sure what u are looking for,to me u are on top of the troubles, IMO won't lessen

Anyway I'm the least one to give any advice

Just looking at those 2 trucks hours, I'm happier still that I bought me a Tripac when I got my truck

I got the last ecm printout at alround 240k miles and ECM time is 4446 Hours, so basically, yes, Apu's are expensive but for those that can have an extra 450lbs hanging in there is worth it.....every penny...
