I have a 110hp tune on the LML. With the Propel HPR diesel, it feels like 130hp. Really zippy , and real quiet.
That's sweet. When I get to Cali I'll have to make sure I find a station that sells Propel. I tried to make it last summer but ran out of time before I had to be back to work. Stayed too long in Colorado and Arizona. Next time I'll make a bee line for the west coast.
My understanding is that with a ninth injector downstream from the engine, extra diesel is not pumped into the cylinders. Therefore there is no washing of the cylinder walls. This only happens with Ford and Ram engines.There is yet another thing to consider as well. If you have an LMM like I do then reducing the regens is beneficial to the longevity of the engine by reducing the washing of the cylinder walls with that raw diesel.
Honestly, that was the strongest reason I can think of for that DPF to fall off. When first I got an LMM I intended to keep it bone stock. Then I learned a bit about he engine and its regen process and was appalled at the manner in which it functioned.
