I feel stupid for asking this because I'm almost certain I have been able to control it in the past, but does anyone know if there are certain operating systems that don't correctly alter the desired rail pressure in the tune? I recently purchased an LMM, and it isn't doing what I want it to do for rail pressure. I thought I might ask here if anyone knows a good OS or calibration I should be looking for before I go through all the stock files I have trying to find one that works. Thanks for the help!
