hi all,
looking to tune my Astra, i have done the airbox and straight through etc. i been told about blanking the EGR valve off, does this make a diffrence? will it give it more of a responce?
Not really, it's a preventative modification. It stops the crap being put back into the inlet manifold, and stops the EGR from breaking, as you remove it from the car.
