Awesome post. New to the forums, but i ordered this car in a SB version, delivery in 3 weeks. I am very interested to hear how the tune works out, I would do that in a heart beat. Also great job with the wheels. I dont think i will lower it as New England roads can be unforgiving!

Thank you and welcome to the forums! Early congratulations on your RS5 SB order. I have already had two dyno sessions testing baseline (stock) and standard S4 MAPs. The results have been quite impressive thus far showing gains of 30AWHP and 36AWTQ and up to 50AWHP/70AWTQ in the midrange. All from standard S4 MAPs! I am late to post the updates here as I have not been able to figure out how to post videos on AudiWorld properly. There will be more updates to come on the JB4 this coming week, as we are testing more aggressive RS5-specific MAPs and E85. So stay tuned! For more up-to-date progress, feel free to follow Project Mystique on Instagram (@importeknika) or on Audizine. I always post there first.

Hello. So, here is the background. I am in a unique situation where my installs are performed by an Audi Master Mechanic as "side work". There are obvious advantages to this including the fact that the work is performed by an Audi Certified Master Mechanic, at an Audi facility where the necessary resources, technical support/data and equipment are readily available and at an establishment were the work will be to specification, reliable and consistent. Again, I have a unique relationship with the dealership where they are fully aware of the modifications and who performed the work. This makes the situation a bit more transparent for all parties involved. Though the cost of having the work done at the dealership is higher, the added security of knowing that the work was done by a certified Audi professional at an Audi facility is worth the added expense and peace of mind, in my opinion.

I have not had a situation arise that required me to take the vehicle in for a problem caused by any of the modifications thus far, nor had my scheduled maintenance and services due as of yet, with only 2K miles on the odometer. However, when I do, they are fully aware of the modifications and I will be sure to remove the JB4 if necessary. The potential for warranty issues is ALWAYS present. All modifications are at our own risk. However, as I stated earlier, my situation is unique due to my relationship with the dealership and the dealership's reputation for being more lenient with modifications. In fact, many of the employees there including a sales manager have race-spec vehicles and regularly race their Audis at the track. For example, I will be joining Audi North Orlando at a charity race event at Sebring International Raceway mid-January. Also, one of their customers has one of the fastest 9-second RS3's in the world.

So again, a dealership has every right to deny a warranty claim due to a modification, but transparency certainly helps. I have had no issues with the adaptive suspension (DRC) and/or magnetic ride control with the H&R VTFs. However, the work was done by an Audi Master Mechanic who is familiar with the technical details of this suspension. I do want to also disclose that Audi North Orlando is one of the top dealerships in R/RS sales in the country with multiple Audi Master Mechanics in-house. Some Audi dealerships do not even have one. So their expertise and knowledge base on these vehicles is much higher than most dealerships.

I hope this sheds some light on the situation.

Audi North Orlando has been fantastic. What event are you going to?

Agreed. The event is WinterFest HPDE at Sebring International Raceway.
