I guess when a statement is made that when using the cam card info you have to adjust the timing events for advance/retarded installs that are ground in. If you move it make adjustments, pretty simple. The card has the correct timing events on it in most every case as evidenced by the lunati events being at a 106C/L. Smart guy but just wrong on this one in most every case regarding the info on the card and being used in the DCR calculator. Add 21 to both sides of that lunati intake event, still comes out to 106 ICL.. I dunno.
