Hello everyone,
You occasionally come across information about boost pressure gauges (or turbo boost gauges).
Somehow, this virus has gotten to me. Not that I don't trust my car

, but it's somehow interesting. I once had a Type 44 as a Quattro 20V with LDA. It was just nice...
Okay, here's my question... I'd like to retrofit an LDA (likely meaning a Lambda sensor display) to my Audi A6, type C4 (with additional gauges). Does anyone know of a reputable manufacturer for this? (preferably a digital one). What's a reasonable price to pay for such a device?
Thank you for your tips!
Regards,
Wool.
