Why do you say that? Just curious.

I'm a little confused by your post. So you're seeing higher boost then normal? How are you getting such an accurate boost reading? Are there any issues besides seeing higher boost numbers? Also, what year truck are we talking here?

Because 26 psi of boost isn't that bad. If you were seeing over 30 psi then I would say you have an issue. If you had sticking turbo vanes or any other air management issues then you should have other driveability issues such as low power taking off. It could also be a few other things such as a biased/mis-reading EBP sensor.

I think he was saying he hadn't seen it that high normally, then it jumped up on him after getting into it. My truck has done that, I think I finally loosened the vanes a bit, but I need to pull it out and clean it.

Gotcha. Well sounds like he might have had an issue before and now it's cleared up! All depends on how he got those readings. Really on a long wide open throttle pull you should be seeing 25+ of boost so his regular numbers sound low.

Your post was kinda confusing. I thought you were seeing only like 22psi. I see 32 psi sock with my tunes and my veins are not sticking. My brother in laws turbo was running up to 28psi and started to run 22-23 max and took it out and found the bearings were bad. Went with a powerror max. You should see 28psi sock.
