Hey guys, so I have a new 2015 A4 bought it brand new, bought the extended warranty I want to tune it. Looked at all the remaping companies. But of course warranty would be voided. So I went to the S4 forums and found a huge discussion about this piggy back thing.

So far I read 22 pages of forums, it's going back and forth questions like is it safe , is it good, does it work , does it affect warranty.
My questions are pretty much the same.
1. Does anyone have this ?
2. How does it work / any problems?
3. Anyone have this for a while and did any major repairs with Audi under warranty ?
4. Does it affect warranty ?
Really any info about this in a A4 would help out . Thanks in advance.
