Mine is a pig too till about 3k. The throttle response sucks too. I am going to give him a call as well. I just figured Id let him be on Labor Day.
I have been driving mine on and off for about a week and a half. It feels better at times than others. But its a pig off the line. I expectred a little better performance down low.

It is not really wierd, it just needs some tweaking. Let Jesse know, he will fix it. The lean to rich dive is Enrichment coming in.
Again Jesse can fix it for you but I would buy EFILive, HP or TC if you are going to be constantly modifying the truck.

The low end response is kinda crappy too the truck chugs and lugs at 1500-1800 RPM's where it never did before. As far as spark knock goes, I haven't seen any hooking my predator handheld up in diagnostics mode and driving. It's just weird how lean it is at 2600 Rpms and just dives into the high 11's. WTF is going on here?

Always try to use the same Dyno or at least the same kind ie: Dynojet, Mustang ect.
