So I'm fairly new to this tdi lark, coming from a few tuned petrol cars I appreciate there's many similarity between the two! My question being who's a good knowledgable tuner? Or who on here knows what they're on about?
Obviously map exhaust cooler ect but ideally only after a good mapper! Maybe one day a cat back, but I've already done high performance and the idea behind the tdi was fuel economy!
Anything I should or shouldn't do while considering a mapper?
I'm in Kent (southeast) but willing to travel if they're worth it.
