Discussion and questions related to the course Practical Diesel Tuning
I have a 2014 lml that seems to have a lack of power I've never touched the fuel tables. I have messed with turning some codes off. When I look at commanded fuel pressures they match actual yet only are hitting around 13000 PSI
That’s definitely telling part of the story. You’ll also want to look at your calculated fuel rate in MM3. That’ll be your biggest tell to see what the fuel rate limit is, or why the truck is down on power.
