I like the red inserts they cost £120 for both alot cheaper than the black ones.Im not to shaw if its been chipped and remaped already cause is really fast and i pulled away from my uncles leon cupra r of a round about.My dad had a 20v turbo which was a 180 bhp and he said it felt faster than that.Would like a bigger turbo if i blow this one up i live near derv doctores so prob go there.
