I read with great interest again, that some people remove their cat from their Disco's and say the result is significantly better. When I tried this with mine about two years ago, the result was very poor. Its a 300 that used to have egr, however it has been removed - so this shouldnt affect performance. Can anyone tell me why mine struggled to achieve 50 mph with no cat in?
Also, I have googled to death trying to find the detailed instructions on using a dial test indicator at the back of the pump, to fine tune it. Does anyone have a copy or know the url to one please?
Many thanks in advance
