Hey all i have just purchased a boost pressure gauge for my ibiza tdi cupra,
2 questions realy, firstly looked for the answer on here but cant find it, before anyone moans

Do you have to drill into your boost pipe (done this on last car) or is there anywhere on the ibiza cupra you can simply add a T piece to pick up the air pressure ?
Secondly could anyone kindly give me some links on where is best to buy a A pilllar gauge holder (52mm) from ?
many thanks
