I have both 2000 and 2002 Cummins Dodges (2000 for sale). On the 2000 I have always had a Van Aiken box, with no problems in 40,000 miles. It will run circles around the 2002 with no box. Obviously want to add a box on 2002. Problem is that Van Aiken, and BD boxes involve pump connector with void sticker. TST box involves piercing wires. That only leaves the Edge EZ which goes into the MAP sensor and the Data plug, neither of which has a sticker. Does anyone have any experience with the EZ. either good or bad? How about using the turnbuckle on the wastegate? I have no gauges (yeh, I know I should, but it's more work than an old **** like me wants to undertake). How does the EZ work without the turnbuckle?
