Why would the 1472F EGT limit no longer work on my '18 3500HD? Only change to the tune is speed limiter gone and added 10% to the DD tables. Now, the EGTs will climb to 1566F then hard stop, which, to me, means this is as high as the sensor can read. I can drive the truck with the EGT gauge, but having the 1472F limit was pretty nice for pulling. Where did it go? Thanks
