Hi all, Im looking to fit oil temp / oil pressure and boost gauges to my audi S3. I test engines at work and fit these kind of gauges for testing purposes but i have a few questions to those who have already installed such instruments. - Has anyone ever used or rated these ?... Sump Plug Adaptor Oil Temp Gauge For VW VAG Audi 1.8T | eBay - Can you upload some pictures of your installations ( Pictures of where you mounted guages / Places that you tapped into for feeds,sendors ) - Where is the best and most accurate place to take the boost reading from ? is there anywhere other than using a fitting on the boost pipe ? - Also if anyone can post links to gauges that they've used that would be useful. Im looking for some discreet gauges / nothing big or in your face, the smaller the better really. Any help or advice , appreciated as always Thanks in advance , Jon.
