Probably been discussed before,but I have blanked my egr with a 2p piece-just fits in the pipe line at the inlet manifold end-just fits inside the gasket ,with a bit of scraping.The inlet manifold is disgusting,full of black snot,but this will have to wait until later,for full cleaning,surprisingly the intercooler looks clean as a whistleThe performance increase is considerable,I can now hold 70mph on any mway hill,and it will now do 80 mph (don't want to blow the old girl up)-even round town I can keep up with traffic,instead of lagging behind.On economy,the last 100 lts of bio have given 615 miles,so ~28 mpg and this was all at 70 -80 mph,(previous before egr blank,was 26mpg)so I am very pleased-just the decat to do now,and an invisible egr blank for 2p
