    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...

I’ll turn the key and let the glow plugs warm for about 5-10 seconds. When I try cranking, it will turn over for a solid 5 seconds or so...
