Ba Xr6T Mods Help?

[xr68yuu]

hi guys im new to having a 03 ba xr6t coming from a wrx its a bit of a change, my question is can anyone help me to find out if its tuned?? I have no previous history about the car since its bought from a car yard but here are the mods I can see:

bosch 044 injectors

50/50 bov

plazmaman pro series 3.5" core front mount

stock turbo (its clean no oil residue cant tell if its been ported or highflowed)

stock boost lines with stranded wastegate actuator

4" down pipe to a 6" cat to 2.75"/2.5" (one or the other) dual tips

walbro 255 ( im gessuing so because I had one in my previous car and it was loud)

f6 typhoon intake

how can I tell if its been tuned? I have no boost gauge but have a mercury gauge, I test drove a stock bf and the boost came on alot stronger on my ba, if I hook up a boost gauge and if its reading more than 5-6psi would this mean its been tuned? (since waste gate lines go to the stock actuator), also more when its cold but it has alot of back pressure from the exhaust sometimes the idle can get lumpy as if the valve springs have been stiffened.

thanks guys

injectors, exhaust + cat, cooler = tuned

valve springs may need an upgrade if its stumbling at idle after some spirited driving.
