Hesitating/Bogging in boost

[shelby_daytona]

Hello,
I just took my 91 Talon TSi AWD for a test drive, and above (i am in canada so units of boost may not be the same) 0.5 kg/cm2 (1/2) on the stock boost guage it will sputter and bog down, when there is no boost it revs up fine and sounds good, but when its above 0.5 (kg/cm2) it wont rev and sounds like its bogging.. i searched for this problem but didnt find any results that matched this problem... if anyone has any ideas, that would be great. I have another one as a parts car if needed.....thanks alot

Thanks for the quick reply. I hate to sound like an idiot here, but how do I go about doing a boost leak test? Obviously pressurize the system and look for leaks? How should i pressurize the system? Thanks alot.....I appreciate it
