hi folks can anybody help me out, ive got a 90bhp tdi i would like to increase this, but all the plugs seem to be 8 or 10 pin on the tuning chips

 

Welcome to the forum. There is a lot of information on the links at the top of the page.

However, although we are a friendly bunch, the majority of people are based in North America, wher Audi doesn't import the TDI.
Someone may be able to point you in the right direction, but it may take some time.

Where are you located?
