Hey guys, I recently saw that tuners can make a ghost cam file for a tune and I'm wondering if any of you have or had this and opinions or thoughts on it. My old S197 I out the Ford racing thumper cams and loved the idle sound with full exhaust. Problem is I can't justify spending what they want for a set of cams for my Mach 1. I'd rather go with a procharger kit. Anyways anyone have opinions on this ghost cam deal?
