I can't tell you what boost you will see but I can give you info from my data logs of 1/4 mile passes at Bandimere Speedway with the 3.875", 3.5", and 3.25" pulleys (06/C6/LS2/1.8 quick lift roller rockers/Kooks Long Tubes).
Readings taken at approx. 6K RPM:
3.875" pulley - 6lbs
3.5" pulley - 8lbs
3.25" pulley - 10lbs

Edelbrock advertises 6lbs of boost for the base 3.8" pulley. Not sure what you will see. I can only tell you what I have experienced. I manually calculate boost based on MAP readings taken from data logs. Example: Map reading of 144Kpa @ 6,200 RPM, converting Kpa to lbs (144 X .1450377377) = 20.885lbs minus the density altitude or in my case 9,000 feet (air pressure for 9K feet is 10.5lbs) which equals 10.385lbs of boost.

Ours puts out 5.5 lbs with headers and hi flo cats. 2011 LS3 3.75" pulley #1591 599hp kit. I thought it would be around 7lbs, but 5.5 is all we're getting. I want to go to the 3.50 pulley, but they are saying it would need bigger injectors as well as a new tune. I didn't think a pound and a half of boost would make that much difference, but they say yes.
