Babymog thanks for the input. I was just thinking that I could (as this is my daily driver) live with the 606 n/a if it had adequate power. I have yet to drive one to determine if I would be satisfied with the performance.
Bustedbenz I will do a little scouting for the dial. The unit on the back of the pump is I believe an electromagnetic switch. Thanks for the suggestion. I will let you know what i find.
