Ok here are my results and Impression..
My
Blanking plate was made out of 1mm shim material and i simply slid it into position on the pipe side of the flange leaving the stock gasket with tangs in it standard spot. I put no tangs on my
blanking shim so it is stelth. I Also put a whisker of flange sealant on it both sides for good measure but not enough to squeeze any out to be obvious.
The Fit turned out to be perfect and i believe 99.9% undetectable by the stealer. I have also spotted the bolt heads with white paint marker factory style so it looks completly normal....
The RESULTS..
Wow, A worthwhile modification. The turbo is way more responsive, I mean way more. The slight hole you fall into of turbo lag when stock is more or less gone. I would say it now has NO lag present now. If it were to have a before and after dyno run im sure there would be a new hump below 2500rpm where the ERG would be bypassing the exhaust gas.
Also no Engine Check Light at all and im sure it will no come any time. I cant see how it is detectable. The ERG valve opperation is normal, but nothing passes through it. There are no pressure switches in the ERG circuit so it is basically a non event.
I am now pleased my inlet no longer recieves sooty hot poison . Only fresh filtered compressed air...
