my brother has an 04 chevy with the LB7 motor in it and has the edge juice with attitude on it with cold air intake and 5 in exhaust and just lifted it 6 inches and wants to recalibrate his speedo and get a little more power but is curious as to what to stack with the edge to get a little more power and get some more economy out of it.
