As I'm not a huge fan of ECU flash upgrades (BMW warranty issues, longevity of engine, stress on diverter valve, etc.....), I was wondering if anyone out there can give me some advice on whether it's worth the money, hastle and possible downstream issues on having a Dinan Flash upgrade done on my new 335i?

Also, it seems to be a hell of a lot more expensive than the UpSolute upgrade I had done on my Audi A4 1.8T Quattro back in 2004! I had the flash upgrade done + diverter valve change for $600.
