ahh ok yeah could be that moving it around when taking it off could loosen grime aswell, thats what am thinking it that mileage all that should be fine, yeah still pulls hard and quicker throttle response from the manifold and decat just the smoke rili. its dropped like 0.1 bar boost thats the only change i can see, ut could that not be from removing the dcat and reducing back pressure?
generally people gain a few psi from adding a decat! Did you use new gaskets when fitting them..ie manifold to block gasket and decat to mani gasket, you may have a slight blow which would explain the drop in psi, if you had a blow you would hear it on idle, kind of sounds like a tractor, any weird noises like that? p.s as mentioned previously...allow a decent warm up..ie stay off boost for the first 10 mins of driving and a decent cool down..stay off boost for the last 10 mins of driving
