    hi, on my a4 tdi (130) its got a few modifications on it, front mount, k&n panel filter, custom exhaust, and decat...

    it has been remmaped also but im having abit of a problem with black smoke bellowing out on mid throttle/boost

    is this normal or is there a fault some where? ive been told by one company that its fairly normaly but if am honest i dont think it is?

    the car drives spot on to be fair good power and pulls fine, just the smoke is an issue!

    the smoke is pretty normal after a remap. As it is probably pumping more fuel in than it can burn to produce the extra power.

    sorry for a bit late reply and off-topic, but is yours a mk2 a4? and if so where did you source the front mount from? is it the same as on the VW bora?
