To be clear the truck doesn't feel like it has any less power than it did before the AEM. In these instances where my throttle input vs level of the acceleration wasn't what I am used to, if I pressed the accelerator a little further than I normally do, the truck accelerated just fine.
I've done a couple full throttle accelerations and the truck felt just as fast as before. I don't have any 0-60 numbers to compare but seat-of-pants feeling is the same as the last 82,000 miles.
My truck had a nearly full tank of diesel (only 44 miles driven) when I had the AEM installed so I'll be able to provide a fairly accurate tank MPG comparison when I fill up again. The Fuelly link in my signature has every tank of diesel documented since the truck was new.
I'll continue to update on my experiences.
