Do you have the latest V2 software in your Quadzilla? That's an absolute "must", it changes everything.
Mapping the fuel curve super easy with the new slider controls on the latest iQuad app update too.
Is the shudder the torque converter lockup clutch slipping? Mine did that (and then fried) when I had a stock transmission, and that was with smaller injectors and an Edge EZ tuner (mild).
You could also have a little too much timing advance in it. Back that off a degree or two and see if it smooths out.
The other possibility is fuel supply, if you have a stock lift pump it may not be supplying adequate fuel pressure for running a tuner. Those should all be ditched and replaced with either a Fass, AirDog, or a mechanical Fuel Boss lift pump setup. The VP44 injector pump doesn't live long unless it has plenty of fuel pressure coming into it.
I'll have to check the version. Can you PM me your number and I can ask you some questions and give you more info on my truck? Thanks!
