James,
This was the exact same thing my dad and I were doing early 02 when he bought his 01 I own now. The duramaximizer was what sold my father and I on diesel performance, Ill always remember the video PPE had of white duramax funning down mustangs and vettes at the track! Was a good time for sure.
Another funny story is the first NEGTG my father and I attended, they raffled off an edge juice(well before the attitude monitor) and the guy who won already had one so I begged my dad to buy it off the guy....so he did! Tony being the instigator he is, came over and showed us how to hook it up, shows us how to set it with the throttle pedal (Level 4 :thumb
and gets a whole bunch of guys from the get-together to go for a ride. He gets my dad to come to full stop and tells him to hold the brakes and bring the RPM's up to 2200 and let off the brakes (knowing the tires would break loose well before that)......to make a long story short, there were two longgggg black strips going down the road and a truck full of guys laughing their asses off. It was a good time for sure and an awesome time to be around and witness.
