nah mate. he defs didn't do any of that ... by his own admission he said it needs the VW mechanic, but his little tune would get me out there safe and sound. before he touch it, once there was some heat in the engine, it would start revving and spluttering at what i'd guess to be around 3500-4000 rpm on idle at lights. one thing he did notice though was ... the carbies aren't webers he doesn't think. some kind of weber imitations.
