Need Engine Advice

Thats the thing with the US, they have some of the lightest gross weights on 5 axles in the world. I think a 5 axle setup in Canada is good for about 87,000. Out in the prairies its flat and a 13L will handle that just fine. Then you get out into the mountains with a super b at around 140,000 you need that big bore engine to get around.

 

I can't give much insight into the delete. Apparently it can be a nightmare to find somebody willing to work on a deleted truck, so that'd be a risk you'd need to weigh.

 

There are horror stories on TTR about badly deleted trucks.

 

Basically when the aftertreatment does a regen, its just heating the DPF up in order to catalyze the soot off. If the engine is working hard, its already making lots of heat.

 

Were you having any problem with injectors why did you replace? Thanks

 

At roughly 500k 2 injectors were operating below spec and truck was running funny , so I had them all changed out for new ones .
