Not firmiliar with the sotp acronym... But it sounds great nice little lope to it, has smoothed out a bit with the tune. I think i'm going to ask if they can lower the idle a little bit to bring it back, plus it jerks a little when I put it in drive when it's cold. Idling around 850, want it down around 6 where it's always been. Either way you can tell it's there and even more when you put your foot down, has a nice ring. Different tone then a stocker. Drives great on the street, awesome acceleration on the highway. Kinda has a surge in power from a stop when it hits 3000 rpm you can feel it start pulling harder throughout the range. I would recommend it, yea it doesn't produce awe inspiring numbers but for me it hit the spot. Tq is your friend and good steady torque she has... Plus I hear it's a good cam for a supercharger which is the direction I'm headin one of these days.
