I hope everyone is having a great holiday season! I really wanted to touch on this single point about the Duramax diesel #1 issue because I think I missed a really good little bit of info when it came to real power loss from a clogged up MAP sensor.

What happens is the MAP sensor or the absolute manifold pressure sensor gets clogged up with soot from the EGR and therefore can no longer read correctly not allowed the engine to know how much air or oxygen is going into the engine. this mean that your duramax Diesel engine is not going to be running at peak performance.

now when I drove this chevy 2500 Diesel after I cleaned up the sensor it was very noticable the power gain that happened. the truck was much more responsive. the turbo boost felt much stronger and in general the truck felt like it had gain some horse power.

I also give into how to clean the sensor, the location of the map sensor on the duramax diesel engine and how to remove and install the map sensor.

so if you guys think your duramax diesel is feeling a little slow and you want to make it faster with more power. check that map sensor to see if it's getting clogged.

anyways guys I hope you have a good rest of the holidays!
