Hi Everyone.....
Ive just come back onto the VW seen, by purchasing a mk4 Golf GTI T 150 on a 2002 reg. But im finding out that the car has been to a company called ABT Sportline. The car itself feels VERY much more responsive than my old GtI, and on closer inspection it has a front mounted intercooler. The other thing im noticing is the MPG which doesnt seem to go over 22mpg on a average run when I drive normal.....

Can anyone shade any light on what ABT might have done to this car. Or what to look for under the bonnet as it all looks the same without removing the engine cover.....
Cheers
