I found this chart that shows the resolution on the 2 bar map. Looks like it reads up to almost 15 pounds of boost. I wouldn't run anymore than 10. So the resolution on the 3 bar would be even worse.

There are guys with LS motors making good power with these cheap Ebay turbos. Most are really cranking the boost up and using them for drag racing. They seem to be holding up pretty good too. I am just looking for 8-10 pounds of boost on my 383 TBI. Mostly for some extra power while towing.
