I'm nervous though about causing myself warranty issues with the known problems people have had or are having with the motor (DI seals, crickets, etc). I'd hate to be stuck with having a car that doesn't run right or a gigantic bill I can't afford to fix it.
Am I overthinking things? Do the improvements possible with a tune actually decrease the likelihood that I would have a problem with the motor?
Just trying to decide if the potential issues are worth the benefit. (oh, and the car is stock in terms of mechanical/exhaust and will mostly stay that way for now)

"Crickets" is a High pressure fuel pump problem fixed by dealer replacing pump.
DI Seal problem caused by detonation (knock) due high RPM throttle transition ignition retard table not active, this is fixed by dealer re-flash , this "fix" is incorporated into OFT ROM's
With the OFT you can always reflash your original map (ROM) when you take car to dealer for service.
Its always possible that the dealer could "detect" that you have recently re flashed a ROM by looking at counters in ECU (engine starts since reflash, or possibly reflash counter), but the ROM that would be their would be the stock rom (assuming you have reflashed it) so its difficult for them to prove anything, however if they are really after you for some reason it may be possible for them to pursue the issue, however I would imagine this would be unlikely.
