Matt _Aero top_ Posted December 8, 2006 Share Posted December 8, 2006 I am sure that has been remarked on previously. If you search I am sure you will come up with the answer Now now don't take the piss :d Quote Link to comment Share on other sites More sharing options...
Guest chris.mcd22 Posted December 8, 2006 Share Posted December 8, 2006 The jspec's wastegate is too small to handle the increase in boost. Therefore, after decatting (removing the back pressure from the exhuast system) boost runs away to crazy levels - hence the need for a restrictor ring in the exhuast to hold it at a sensible level. The UK spec has a larger wastegate which CAN handle the increase in boost and will keep it below 0.9bar (ish). To raise boost past the wastegate level you need a boost controller (Or do it the poor mans way with a bleed valve) Ah ok cool cool. Thanks for the info. How does everyone pass their mot after they have decatted ? Decatting is an mot failure is it not? Quote Link to comment Share on other sites More sharing options...

Thorin Posted December 8, 2006 Share Posted December 8, 2006 Ah ok cool cool. Thanks for the info. How does everyone pass their mot after they have decatted ? Decatting is an mot failure is it not? Find a friendly MOT tester or refit the second cat before the test. Quote Link to comment Share on other sites More sharing options...
