Well I installed the Powermax last night. The only problem was my first call to TST they told me I did not have to hook up the EZ to the MAP sensor. Well that did not work. The truck started and sounded like it was idling on 3 cyl. I then removed the EZ and all was fine. Then I re-stalled the EZ by chaining the MAP cables together with the Powermax MAP cable first then the EZ. I called Mark today at TST and he told me that is the way to do it. Just to make sure that the Powermax MAP cable is first on the sensor chain. So far so good. No codes!! I am running the EZ on level 3. I am going on a 500mi trip this weekend so I will see the long term results. The power is unbelievable. All I can say is WOW!!
I tried it with both on lvl 7 and it slammed me in my seat.
