Turbo leak? Mpg issues

[cja7928]

I've been fighting low mpg, so far I found a bad icp sensor, bad ebp sensor and clogged tube. I've got 4" exhaust, volant intake, dp 60 economy tune. New fuel filter, changed all the fluids. I'm getting 2 psi boost on the freeway and 22 max wot. I made diy pressure check and pressurized the intake to 15 psi and it's capped right before this spider so it won't leak air past the exhaust valves. It is leaking air out the rod that actuates the ebp valve, and the intake will only get up 4 psi. Is this a normal place for pressure to escape? I'm not familiar with the internals of the turbo but I would have expected a boot be leaking or something. Seems weird to have air leaking past the ebp valve actuator rod?

Check the boots going from the spyder to the engine, mine leaked there and caused
problems. They are hard to see down there, should be orange but I bet they are oil
soaked black.
Cant help you with the rod, I swapped mine out with non-ebpv pedestal and added a high
flow exhaust flange just to get rid of that thing.

Im thinking about swapping to a non ebp pedestal as well. I found what it was - I forgot to plug the ccv so it was pressurizing the crank case and blowing air up through the bottom of the pedestal. Once I plugged the ccv it held pressure just fine - no leaks at all. Does 2 psi boost while cruising seem low?

what is the EBPV and why would someone get rid of it???

They may want to get rid of it for a number of reasons. First off, they could have a leaking actuating rod. Second, they may already have it unplugged and don't use the EBPV. Third, some claim it can lower EGTs by up to 50*. I'm sure there are other reasons, those are just some of the common ones.
