i was talking in the context of the o/p and his intercooler issue. for things like that im sure the majority of older mechanics will be clued up enough to comment.not always sure enough though.
are there many tuners breaking new ground and inventing new stuff or just working to tried and tested known routes?
perhaps im oversimplifying it but i wopuldnt consider using specific tools of the trade to do specific jobs to already known tollerences as particularly new or groundbreaking but just another slightly more advanced level of what the mechanic will do.
