RE: 2350 cold weather MCF table adjustment Update, Adjusted the VGT table between 1500-1800rpm at around 3/4 fuel. Values in yellow were all lowered 2%. Tested all week and it’s working well keeping boost in that 32-33psi max while pulling hard.. I do need to make a few more adjustments at 15-1600 at 1/2fuel, I’m seeing the boost really jump fast when I get into the overdrive gears pushing up to 34 psi then dropping down. Overall It’s in the right direction. I also replaced the imap sensor to take any possible pressure error out of the equation. While I was in the program I also lowered the torque tables under 1500 rpm down to 1850ft/lbs from 2050ft/lbs. I never pull below 1500rpm so I don’t notice any difference but it will keep the abuse down of someone else is running the truck. User's Signature: 2015 389 Peterbilt.
