i just ordered a tt chip from turbotweakstore.com and i think if you answer the cam question with "oem stock" eric will know what to do. On the injectors - there's a part number on the injector but on mine it's very, very small writing on the plug. You'll almost certainly have to pull the injector to see it. And - (not to question your knowledge of your own car) but i'd want to see the number because injectors seem to be one thing that almost everyone changes on these cars so unless it's a 1 owner you really want to make sure they haven't been changed... Just my 2cents.
