The engines in question are V6 diesel engines?
It is also important to know in which models are the engines used, as the torque output is different from the same engine.
These engines are used in 2010 and 2011 motor homes. Same models different years.
154 hp -- 2010
188hp -- 2011
154hp has 280 LB/FT Torque and 188hp- 295 ft·lbf
Thank you that solved the puzzle.
Both are the same engines, difference is in the engine management.
I assum you mean chip change
With the different software, you should be able to get 188 out of 155 engine. Of course, it can lead to warranty problems.
From the factory, the difference is more serious though
188 might have a different turbocharger.
I do understand. I worked a similar problem with a CAT diesel
Ok, let me know if i can help you further.
