Well I've ran a 1.8t for 10 years in a Vw Passat guise and had de catted it just before it was moved on. Now it was approaching 190,000 miles but still went well, after the de cat there was a useful increase in torque, revability and mpg but the one thing that ruined it was the smell. A strong petrol smell and quite nippy on the eyes. I had an 02 spacer on the rear sensor and the CEL never ever came on.
My question is would this be down to the mileage or maybe a blocked PCV system. I'd just like to hear from those of you who've de catted you're cars and your experience.
Having moved on to a B6 A4 1.8t Quattro I feel this would give it a useful torque increase. The car is in standard trim other than the fact that I've port matched the exhaust manifold and I've also recently opened up the exhaust turbine side as well, it has made an improvement but I think the de cat would be the icing on the cake. I know it could be remapped but the funds aren't forthcoming, thanks in advance for any replies.
