you can adjust it yourself buy adjusting the wast gate on the turbo. how sure are you that the guy adjusted the boost or he could be making an excuse for a leaky exhaust manifold

lol, i agree with bigkriss it sounds quite odd
i cant think of any reason why someone would drop the boost below the stock level on a stock standard ca18det, im afraid theres most probably something wrong there, turbo shot, leaky manifold, leaky boost pipes or intercooler....... could be a few things, plus i havent seen any adjustments for boost on the stock T25 turbo, you can connect the vacuum line from the waste gate actuator directly onto the vacuum nipple on the turbo, perhaps the boost cut solenoid is faulty or something, but if its smoking then you gonna have to get turbo checked
