No i did not. stock it boosted 15 psi and then with dp like 13. You very well might have something else going on besides this. From what I have heard boosting at 6psi is the ecu going into limp mode due to various reasons, hard to speculate until you find out what the code is.

Learn-Down!
I just looked at your location it's approx 0c... + you just added in a downpipe.. which is suppose to make a decent amount of hp
It sounds to me like it's just learn down in action...
Colder Air = More Power = Learn Down = Less Boost
Catless Downpipe = More Power = Learn Down = Less Boost
But still check the cel...
Edit: Stock you should be able to boost alot higher than 13psi.. "did you just get this car in the colder months"

evap shouldnt be coming up...
you should only be getting a catalyst efficiency code
disconnect your battery for 20 mins then try again, should learn it... you may have jut thrown the fuel trims off a bit

yes they are tightened no cracks or leaks that i can see i checked the hoses.
i noticed when i opened the hood the dipstick wasn't seated in and was sticking out a few inches
didnt do any thing different still low boost and the gaskets are like new
