Hello guys, this is my very first thread @ Camaro6 and unfortunately its a problem

, a while ago I've bought an LT4 supercharger off a friend's C7 Z06, sent the supercharger inlet to ADM Performance and installed the 2.55 pulley, installed the unit on my SS Camaro with headers, exhaust, roto fab intake and a methanol injection, lower pulley was stock and the car made 10 pounds of boost with no issues at all

, now decided to go with a built 416ci LT1 with a 10.4:1 CR, a custom Texas Speed camshaft and a lower 15% ATI overdrive, just broke in the new motor and put the car on dyno with a base tune with maybe 10 or 11 degrees of timing and an AFR around 10.5 car only made 7-8 pounds of boost with 550-616 hp-tq, talked to a friend and he told me that if it went more lean it'll make some more boost, so decided to go 11.5 on the AFR with 15 degrees of timing, and boost keeps going around 8-9-10 over and over, also I changed the belt couple of times and tried a smaller one, same boost.

I really don't know if that's the normal boost or my boost gauge is broken or there's something else wrong that I don't get, please help.
