Hi, been a member for a while but never posted and now getting back in the game here. Bout 7 months ago I installed dragon fire 840 big bore kit, stage 2 cam, over drive plate, full exhaust, larger tires, and of us course a msd charge fi which brings me to my question. setting up tune for all this? Any suggestions. I have other projects and plus msd sent a bad tuner the first run so took a while to get that fixed but now I need to get this thing going good.
