First and foremost I would like to introduce myself. I just moved up from the n52 to the n54. I had a few very simple questions which I would like to hear different answers for.
How long is the hpfp warranty, and other turbo related warranties, and which performance mods can I do which when reversed, could not be detected, so I can get warranty work done?
Looking forward to some answers.
I was thinking DCAI, bov, exhaust, but I was unsure if a tune would be detected (if not, which one)
