Overboosting?

i have a question for you guys. i have read alot about trucks like mine making boost around 25 to 29 lbs. but for some reason when i get on my truck it makes about 35lbs. it shoots straight up to thirty and then gradually gets to 35 in about 2 seconds. am i overboosting? i have the wastegate unplugged and my mods are listed below. what do you guys think?

oh and another question, i have no check or warning lights coming on but it feels as if my truck defuels when i hit like 25 lbs. will the boost ann. work on my truck? does it give more smoke?

thanks for your responses in advance. its really appreciated.

first thing. get rid of the k&n i had one once too. but when you start boosting at high levels bad news. dont learn the hard way. number two i have a diablo tune too and i dont like it at all. im waiting for my truck to get in to a local shop for a better custom tune. im suprised you dont have a warning light after 31 psi. thats when my kicks in i dont know that theres a difference in 01 to 00 besides the rods. sorry you probably have the bad ones depending on you production date. but i dont dont think you are over boosting. stock turbo right?

well i've been told when running too much boost... 55psi with the H2E that you will actually suck the air filter oil in through the turbo. but i might have been given false information. i got ride of mine cause ive already gone through one turbo... racing an elcipse bumpin his music yo! but i got him no worries

There really shouldn't be enough oil in the filter to hurt a turbo. The filter should be virtually dry to the touch. The problem I heard is that it's filtering efficiency not good enough for a turbo charged engine. It lets too many particles through when you start sucking on it hard. That=bad for the turbo.

I could be wrong, but I don't think the oil is a problem. You are already sucking oil out onto the turbo from the crankcase vent (unless you re-routed it), and that doesn't hurt anything.
