welcome! that boost gauge on there is a mechanical gauge that reads in 'bar' the metric equivalent of PSI. When its - the car is in vacuum (off boost) when its + you are on boost. If the highest it gets is +.5 somethings up because that is only about 7psi. The car should be hitting around 13psi at full boost or .9 bar. Have someone drive with you to get a good look at it while on WOT. The stock boost gauge is not the most accurate or easy to read, so you might be ok.
One of the most telltale signs that the car has been modded is check the turbo heatshield. If its cut or is missing completely, the car was most likely not kept stock.
I would take the car to a tuning shop that is versed w/ Subarus and get them to check the car out. Many dealers don't know crap about modifications or what is or is not stock. Many times they misdiagnose mods as COSTLY engine problems when sometimes they are as minor as a loose vacuum hose. I have had car dealers try and tell me that the boost gauge was a clock...
The 04 stock wrx will not be as quick as the 2.5 liter versions. Plus if your 04 is truly stock then there is significant lag due to the catted up/pipe. Plus it sounds like you might have a boost leak.
