Hi All I had some more dyno time last week due to cold idle pulse, it was decided to put the Cat back in, and some work was done for the injectors, The new run showed 350Kw. I the 300km drive home, I notice the farting has become a lot more subtle. It must be a combo of exhaust and tuning. The guys said they dont adjust the ZF tune at all and it use to fart like a drunk Irishman (old tune 336Kw and No Cat)
