Egr allows the exhaust gas to go somewhere else other than the turbo. So when it is completely blocked all the gas goes through the turbo this can make them respond a little better. Yes its overboosting but it may only be at that setpoint in the ecu. You may get away with 20psi but it will have to be beyond say 2400rpm. Unfortunately all these ecus and vehicles arent exactly the same so you do end up with some that will fault at lower psi while others can be pushed to even beyond 20psi without issue.

Yea absolutely..
Just really weird how some do and others don't. .
Any negatives at running 17 psi? ?
Garret says efficiency runs out at 19psi..
But can stock internals handle that boost??
Might grab a zd and rebuild it..
Mod a few bits like ceramic and tyflon the pistons, work the head a bit lol..
Ow wifie would love that.. haha..

As an example I think Kevin07's was good for 16PSI yet Mudski and myself can achieve 20-25 with no dramas
I'm in the process of reducing my boost so its 12psi @ 100kph and leave it at that lol.
My boost is all over the place atm since I change where I get the boost from. easy enough to sort IMO
Would you really notice any difference on a CRD dialled in at 17psi compared to 19 psi.lol
