If you leave the valve plugged in you dont need a special tune...and with the valve there and no block off plate in place i dought they will see that the cooler is gone under the intake it would take some looking!!I'm wondering if deleting the EGR will cause the tailpipe emissions to fail, even with a tune written specifically for it. Obviously, if the govt opens the hood and has a look it will fail...anyone been through emissions testing with one and a stock tune?
ya all these are options but if you want it to be undetectible id do a up pipe the collant pipe and leave the valve there...No tuning needed no CEL and no inspector is gonna notice if you leave the valve...My egr del was 2 plugs and a little welding with my mig welder! Costed about 3$
