Hi all,
Current situation is that I still have the first CAT on the EXT system at the moment following the MOT. It is usally running with just a restrictor ring in..
Do you think with the CAT in aswell would cause the car running problems? Seems, or feels like the car is misfiring now and again, and sometimes boggs down when the second turbo starts to kick in.
Any feedback would be great thanks.. BTW, not planning on running it with the CAT in for long, will return it back to full decat soon, but just wondering if it would cause any problems like mentioned above. Or should I start to look at anything else..
Its very odd as I have just noticed it. And the only thing that has changed is the CAT in and I moved the BLITZ SUS air filter to a different posistion (Nothing drastic, just closer to cold air feed pipe, which involved moving it few inches to the right)
Sorry for the long post. Quite worried about this.
