nismo_lp Posted January 27, 2006 Share Posted January 27, 2006 I only have 1 of my cats removed and i get fuel cut at around 6000 revs .... is this right??? I thought the boost would only creep over 1 bar once the cars been fully de-catted? Link to comment Share on other sites More sharing options...

Stu_Fraser Posted January 27, 2006 Share Posted January 27, 2006 I got 1.2 bar with just my first cat out. Link to comment Share on other sites More sharing options...
nismo_lp Posted January 27, 2006 Author Share Posted January 27, 2006 I got 1.2 bar with just my first cat out. That would be it then ... and basically yes its standard apart from the exhaust! Time for the full de-cat and fuel cut defender i think! Link to comment Share on other sites More sharing options...
terawua Posted January 27, 2006 Share Posted January 27, 2006 The first CAT makes much more difference than the second CAT in terms of exhaust backpressure. Link to comment Share on other sites More sharing options...
nismo_lp Posted January 27, 2006 Author Share Posted January 27, 2006 The first cat being the closest to the engine? Link to comment Share on other sites More sharing options...

nismo_lp Posted January 27, 2006 Author Share Posted January 27, 2006 Thats the 1 i still have fitted ... wonder why my boost has gone up so much. Oh well ... il sort it out before the dry weather Link to comment Share on other sites More sharing options...
terawua Posted January 27, 2006 Share Posted January 27, 2006 my first cat is out and I am getting 1.05 BAR ish with the first one in but no fuel cut (yet). I have TRL FCD and a fields, so I am just going to pop all that in this weekend, and put the first decat in to see how it goes then. Remember the cold weather will make a difference too - denser air at low temperatures... Link to comment Share on other sites More sharing options...
Stu_Fraser Posted January 27, 2006 Share Posted January 27, 2006 Every car is different matey, like you said get yourself a full decat, restrictor ring and FCD and you will be laughing. Would also be wise to change your plugs and maybe your fuel pump. Link to comment Share on other sites More sharing options...
