Holley Sniper progressive linkage stumble?

It’s going to get frustrating having to take your car in every time you’d like to change part of the tune. You should get a laptop and download the tuning software and learn how to adjust it. Once you start working with it, it’s pretty easy to make simple changes. Especially so if you can data log and tune from the log.

I suppose so. I have a Mac Pro laptop but I hate using PC software on it. I guess however that my real question was "does this sound like a low throttle stumble or am I imagining it"? After getting my car back from the shop after the transmission swap and throttle linkage adjustment (among other things) I'm not 100% happy with the off throttle acceleration until after I reach 2000 rpm's. I'm just trying to figure out the issue before I talk to the shop again.
