Its been about two days since I uploaded the revised tune from Mike into my computer. I just got home from the dyno today. The good news is my check engine light has not come back on, with the rich codes bank 1 and 2. However the truck is running rich again. I will post the dyno graph when I get it scanned.

 

Here is my most recent dyno graph:

 

well looks like 1 more adjustment and you'll be sitting pretty!
I wonder if 1 of those powerdyne supercharger units would work on a 2006 4.2 V-6?

 

I hope so, its starting to get a bit expensive going back and forth to the dyno at $75 bucks a pop for 3 pulls

 

Bad news, check engine came back on today, p0172/0175 banks 1 and 2 rich.
