In the middle of "adjusting" an LBZ truck with a larger VGT for sled pulling. The log files show the MAP sensor is maxing out at 39.01psi (NOT including barometer pressure). I was talking to the owner and we were thinking of installing a 5 bar MAP sensor, 0-5V, adapted so it could be read through the factory harness. I have seen in other forum post (https://www.duramaxdiesels.com/forum/threads/how-to-lmm-os-map-scaling.71271/) where .cax (or .cax8) files were added to enable rescale the MAP sensor, but none done for the LBZ. I know on the LLY's you can adjust the B0202 easily for this, but that table was remapped for altitude in the LBZ. Truck is currently running the 52604138 OS.

Any thoughts?

Yeah know I was thinking we did that for the LBZ also, but link is in EFIlive forum maybe. Either way, check over there, and post the question if ya don't find it. That's where I got the original cax file to do it the LMM.
