Too big Injetors?
I agree. 140's would honestly be a bit laggy on a 66... They probably say that just to cover their own a**. If you have the money I would leave the injectors and plate and do a 62mm turbo. You'll be very happy with it. A turbo upgrade is one on the best possible things you can do to these things.

These trucks do stumble a little bit at idle with fuel mods. Big injectors and pump tuning will definitely cause it. It's not really a problem. You will notice it the most when you get off the highway as the truck is running the hottest at that point, and the fuel is thin because of re-circulation. Most modded trucks do have a miss-like idle.

How hot are you getting? I was thinking about running some 5X.014 and 191 delivery valves 100 plate and then everything else in my sig is up to date using the stock turbo.

You should worry about the turbo though. Anything over 32-34 pounds puts a h1c out of its map and then results in drive pressure issues, super hot air, and a shortened life on the charger.
