Hi All,
I have been having some issues with my B5 1.8T lately and ended up knocking through the standard CAT.
However, since doing this, the car seems to have a lot of lag and takes a second or so to come to life. I've cleaned the spark plugs and checked fault codes (none for engine) so am abit baffled.
Could it be lambda related? Also, I've had a remap so wondered if the ratios were abit out.
Any help would be greatl appreciated
