EGR blocked today...

[the evil twin]

As Lemo79 said, you will need to take boost control away from the ECU now that the ERG is blocked. Otherwise you will be running low boost when you least want it.

Uuummmm... never ever had low boost on mine and it was fully instrumented.
The ECU will still boost similar MAP with/without EGR overall and if anything my boost was higher till I tweaked the VNT to reduce boost pressures.
EGR block my cruise boost stayed around the same, put the welly in and the boost was momentarily higher post EGR block at around 36 to 38 PSIA
Had to tweak the VNT because of higher boost due to the EGR valve not cycling like the ECU was proggy'd to expect so reduced the MAP to around 32 PSIA max.
