This is what is keeping me from doing any tune on my car, after really wanting to. I can't throw away the warranty for this car. Once that is over though, if I have the car and the funds I'll be looking forward to it.
I’m with you but I don’t know how long I can hold off. The warranty lasts a lot of miles. If I consider the full emissions warranty that would end up being another 80,000 miles for me. That is a couple thousand hours of driving. And there is an opportunity cost to not being able to drive an improved car for all those hours. Then I consider the fact that the car can be flashed back to stock for warranty work and may not be flagged (I’ve yet to read of a tuned-only VW TDI, flashed back to stock, being denied warranty coverage). And add the fact that there may not be any issues that need coverage (our 2011 JSW went 125k with no service or repairs except fluids and tires). It starts to become a harder decision.
I've thought about buying a tune as well and waiting, but decided to spend the money elsewhere for now. If I'm predicting right, I'll pass 123k miles on the clock by mid 2020, and that is two years away, about lining up with my CPO expiring. I can't risk throwing away the money I spent to make this a CPO car. Everyone else is free to do as they wish, I don't know for certain about denial of warranty issues but my own risk analysis says don't do it. Until then I'm learning how to adapt my driving habits to better utilize the car. It is a work in progress but I am improving.
