Turbo Makes Boost, however there is no power

[PetefromtheStreets]

He actually did put the greddy kit back on and it ran just fine. So it's not the piston rings.

Now that's nuts!

Turbo possibly blew a seal and is letting air into the pan through it?

That was the initial thought, he sent it to Garrett and they said it was fine. He also recently said the turbo is fine, although didn't say why he deducted that. But to me, the only major things changed from setups is the turbo and the turbo manifold. It obviously isn't a leak in the charge piping since the map sensor reads the boost, it isn't a leak in the IM or with piston rings because the greddy kit makes power just fine...

Same bov being used on both setups? Not just same brand but exact same one?

It has to be in his calibration/tune or in the install from kit to kit.

Seems to me that I read he is also changing wg and bov when going between the two kits .I think the issue is related to those or the install .However the test video of the turbo does seem odd to me but I can't say I have ever tested mine like that and checked for air coming out of the oil drain or coolant ports.Garrett told him it was normal which also does not seem normal but they are the experts .I just don't see how the turbo produces the set 6 psi how it would make no power or not be able to go beyond that boost level an odd situation.Lets face it exhaust happens turbo spins = boost it has to be something besides the turbo imo . However knowing who is tuning it I highly doubt / am certain the tuner is NOT the issue as Vit tunes many cars and I think he certainly knows his stuff .
