I hady MK4 pd130 mapped to 180 and it smoked like a bitch which really got to me.

Black smoke is unburned fuel (too much being injected against the amount of air) . A quality custom map should smoke very little (or not at all) :happy2: (R-Tech Nick will do you a proper map  :notworthy:)

I thought that petrol cars mapped should smoke a bit when given 'the beans' as they generally run rich to protect the engine? :confused:

My petrol GTI chucks a small amount out as it's mapped to run a lil rich at WOT to protect the components.

Lots of generic diesel maps smoke as they aren't custom to the car, also diesel engines aren't as fussy about air /fuel ratio like petrol cars are so diesel maps are generally mapped a bit rich as protection for the engine (without affecting power)
