Holy Boost!!

Ok so I totally expected to lose some boost after oil cooler, egr delete...etc. Instead I show 32PSI just stepping into WOT where before I showed 27-28PSI tops WOT hammer down for a bit. Should I be worried about the extra boost?

I did a turbo reconditioning while it was out and updated the oil feed/drain tubes. I just don't understand why I'm showing extra boost and most are showing loss. Somebody smarter than me please explain.

Possibly before you cleaned the turbo it was sticking and not allowing the vanes to move to reach more boost.

Yea I cleaned that bad boy up! It wasn't bad at all. The only signs of wear/sticking were under the vanes themselves around the post there was a rusty build up of soot and grime that created a "high" spot that I could see slowing the vane sweep down and later down the road it would lead to some major sticking. I thought I wasted a little coin but now that I see those boost numbers..... I should've cleaned it twice!

What he said anything over 28lbs will possibly lift heads just something to remember...if you have ARPs I think you will be ok.

It's more the back pressure that lifts heads quickly, than actual boost does.
