Losing Boost

This is my situation, maybe someone can lend some advice.

I have a 3.5MSP. I have been noticing a drop in my boost level...it now appears that I'm only hitting 4psi. This is after:

1) I changed the vacuum lines about 6-8 weeks ago. I did not note a loss in boost at that time. I will admit however that the lines behind the motor maybe off by a fraction of an inch. I have two different size silicon hoses and I think think that I may have got a little mixed up when I was cutting and putting them on. They all went on fitting tight and without too much effort. Aswell they are all clamped.

2) Replaced tires 2-3 weeks ago. Pirelli 210 Snowsport 195/60/15. (Lots of fun!)

3) Winter came and has been significantly below zero since I bought the tires...a day before even...I am an occasional procrastinator.(drunk)

I have also noticed a significant increase in gas mileage (which IS much appeciated)...and no, this is not due to speed reduction because of the bad weather

I am just wondering if this is normal or am I going back to the dealership yet again.

oh...no MBC on the car at current time... fuel cut
