does anyone know why?
I have just fitted a collins twin piston dumpvalve to my 2003 convertible turbo. Everything was done correctly by a mechanic (close off oe dump and so on...). This is the only thing change with the car the rest in standard.
All is going well with turbo and dump valve BUT only one thing. Yesterday it tried to cut out on me twice. Never cut out but lights on dash came on. The lights in middle of rev counter which come on when ignition is on. I notice aswell my revs lowered below 1000.
I have notice a drop in revs on idling aswell only by abit. I no nothing about cars so can someone help.
do the revs need highering up slightly or something.
any help is very appreciated thank you
I think thats a problem you get with blanking off the oe D/V, most people run the oe with the aftermarker one together seems to work ok just not as loud
