i had a question about the mm3 exhaust back pressure pid. just installed the programmer today and setup my display. i noticed the ebp pid starts out showing 14 psi which is an absolute reading i believe and when i go to change the range setttings it only allows a max of 10 psi? is there something wrong or am i using the wrong pid for exhaust back pressure. this is on my 2012 ram. thanks in advance.
