Looking to get back into my A8 4.0T soon. Currently driving a Cayenne Turbo and had very good experience with VRTuned flash on my Porsche. I know how Audi is with flash tunes and therefore will not be getting one. However, a piggyback tune maybe the answer for those of us looking for additional HP and ability to pull it when going in for service.

I'm going to try this piggyback as soon as I get back into the Audi, but wanted to pass this information along in the meantime and see if anyone else tried a piggyback on the 4.0T.

VRTuned has been good to my Porsche with good support, so I am expecting nothing less from this product:

What do you mean, how Audi is with flash tunes?

In the past, in the U.S. market AOA has instructed their dealers that any engine software modifications made by owners VOIDS the warranty. Furthermore, dealers that agree to service any known "tuned" vehicle places their franchise agreement in jeopardy. Supposedly, any Audi with a tune/chip or other engine/transmission software modification that goes into a dealer's service department and gets connected to the Audi service computer system can be flagged, which leaves the dealer no latitude but to deny service. At least this is what has been mentioned on the various AW forums.

Correct. That is why I was looking for a piggyback system that can be easily put on and taken off. I loved APR on my V10 S6, but the days that dealer turned a blind eye towards modifications is long gone. So unfortunately I will not be putting APR on my CPO car, but I'm hoping a good piggyback is a viable solution for extra power. A lot of reputable tuners are going the piggyback route, even Dinan for BMW.

MTM is a piggyback as well: MTM > Products > Produkt Information > MTM M-Cantronic, F-Cantronic, V-Cantronic, S-Cantronic

Seems like the best of both worlds, around 100 extra HP and keep the warranty. I'm doing the VRTune as soon as I have my A8L 4.0T back 100% of the time so there are no mistakes how it will go in for service.

DirtyVegasTT

Not true! They got one for the 3.0T as well:

Wow, I'm definitely going to get a 4.0t now. Those are so numbers without the price or insurance.

Placed the order this AM. Hopefully can receive and install it by the end of the week. Read about guys being happy with this setup on their S7 and S6 on Audizine.

I'm excited to hear the results... I had a piggy back tuner on my 2014 BMW 535d and it made a HUGE difference across the board.

I just contacted VR and they are telling me the Tuner Box is $1,500 for my 2015. I thought they were $1,000??
