Hey guys. what setting do you use with the spark arrestor in? Trinity setting is 5,3,3 (mode 1,2,3 respectively) out of the box for no arrestor and no lid. I backed off to 4 for mode 1 (idle) when running it with the arrestor in and no lid. It idled better. Should I adjust mode 2 (accel) or 3 (full throttle) when running it with the arrestor? how about the arrestor and lid? Trinity tech said I might have to back off to 2 in mode 3. Also, do your exhausts leave carbon where the mid joins the headers? fix?
