No boost???

[NJSERRANO]

Last night I was driving home on the freeway. I got on it twice to make a couple lane changes...the truck had plenty of power and boost. After I exited the freeway, I noticed that when I gave it some gas, it wouldn't make any boost...only getting out of vacuum under throttle. The truck is pretty stock except for the following:

kenne bell chip ( I think )
kenne bell cai
borla cat back w/hi-flo cat
all ignition and fuel tune-ups within last 1k mi

What are a few things that I should check for?
-wastegate issue maybe?

Re: No boost???

I would take the elbow off the turbo inlet and make sure its not seized up. If it spins freely and no more than normal movement, side to side in and out, I would say it's okay. After that, check the waste gate. Make sure it's not hanging up or linkage from waste gate actuator is not off.

Re: No boost???

I'm retarded, it's fine. I tried it again tonight at same spots on my way home. Thanks though.

I think the truck needed to downshift because I was in the wrong gear...it was just taking too long to spool up.
