Given that we now have the R35 chit-chat merged and that the relevant thread title is not that descriptive I wanted to highlight everyones attention to this thread:
Anybody having engine problems yet or has heard of??
Basically a 2 month-old Euro GTR has blown it's engine and has had the warranty denied, due to a Cobb tune.
Whilst from the description of the problem it seems unlikely that the tuning caused this, it is never-the-less very important that anyone considering tuning their GTR knows that Nissan Europe will deny your warranty and that engine failures are happening. This is now the third known engine failure (the thread relates the story of a Swiss car and German Press car that suffered similar fates).
What I'd love to see is someone offer a tune that included warranty. It is done on Porsches by a number of tuners and it was the prime reason I went to Ruf for mine, as they offered a 2 year warranty.
