i fixed a boost leak and now i am hitting 14lbs so now i have questions
On the dyno my car peaked at 11lbs but today I found a decent size boost leak coming right out of the snail of the blower where it connects to the discharge pipe. I fixed it and took it out and my boost gauge hit 14lbs. And I don't know for sure what pulley I even have but when I measured it it looks like I have a 3.33" and I also have a andersonpower pipe. But my question is since im tuned for 11lbs how much do I have to worry about? My wideband is still reading 11.5 when I am n the throttle so I am not leaning out so im not worried about that but do I have anything else in the tune to worry about that I should get checked out?

On a 3.33 pulley you should not be seeing 14psi if you are intercooled. Especially if you are cammed. Should be more like 8-9psi not 11 and definitely not 14. 14psi is very dangerous on the stock short block.

I Thought it was that is why i put this post up. But on the dyno i was seeing 11lbs on every pull, so i am 100% positive i am running 11lbs, now the 14lbs i am wondering if my boost gauge is messing up. And my tuner said my power pipe got me from 9lbs-11lbs, he said it gave me a extra 2 lbs

Deff the colder air I noticed it with my car normally were I only see 15 psi I was seeing 20 psi so I'm guessing I would have maxed out at 23-24 psi were my max on the dyno was 20.5 psi
