Hey Mate, I haven't been around for a while, playing with my XR4.... Economy has been my down fall, I thought it was going to drop, now sitting on an average of 22, rather than 20, so I was going to contact Clinton and ask if he could help at all, I was planning on a cat change and a ZF massage as well, and was very interested in yours for the fact that Clinton changed the ZF settings, do you know what he did? He was very much against doing anything with the ZF when I asked last year. Also who did your cat change and what type is it andy more specific details. Cheers
