REF I have the same setup as you, minus the fresh tranny.
I'm interested in your new tuners performance. My DP tuner is my first tuner experience so I have no reference as to how it should perform. I have 20,40, 60, 80 & 100 hp tunes. The power increase in the 20hp is pretty amazing. All the other tunes dump so much "rolling coal" I rarely use them. But even in the mild 20hp tune I have to drive with the EGT gauge rather then the throttle when climbing a Colorado mtn grade.
It seems that a 4 speed auto on a +8,000# van is subject to critical shift points and gearing to keep from "rolling coal" all too often.
Looking for your feedback on the new tranny & tuner combo.

If you are in the springs I would check out Matt at 3D Offroad (they just moved to 3420 Chelton Loop out east). Great fab shop but knows the 7.3 well. Did all my work on mine before I sold it. Had I kept it he was going to fab up an intercooler and do water meth on it, performance chip etc.

7.3L Performance Shop / Turbo Upgrade Question through or reference the end of this linked thread for my impressions on the PHP tuner, all positive so far, with none of the side effects found with the DP “no tuner”
