Help 2gmas conversion

[snowboard1]

I just installed a 2gmas in my 1g and now my stock boost gauge doesnt read the right amount of boost. When I had my 1g mas in, the stock boost gauge worked perfect, pound for pound on my autometer. Since I installed the 2gmas the stock boost gauge is off like -4 lbs, and wont read any higher than 12lbs. even when running 17 lbs of boost!
Im just wondering if this is normal ?
I soldered the wires according to vfaq.

Well you need to get a real boost gauge. Yours is reading what the ecu thinks its boosting. Adding a simple mod like a kn filter mess up the count! You need to get an aftermarket one

I do have an aftermarket one like I said, its an autometer.

The stock boost gauge takes its airflow readings from the maf and tranlates them into boost. When you upgrade to a higher flowing maf, it will make the boost gauge read lower than with the stock maf. This is normal and one of the reasons why the stocker is useless on anything other than a bone stock vehicle.
