Now, that's a bold statement to make '09GTR!
Actually I have, by two very reputable tuning houses (legends in their own mind, masters of their own retoric): two cars blew up and it took the vehicles' manufacturers, with a bit of good old legal encouragement,
to come to the party, not the highly skilled tuners, to replace an engine in one and a transmission in the other.
That is why I am so reluctant to tune this rather pricy car outside the warranty...oh, and the fact that, like 90% of enthusiastic modders on this forum, I haven't yet learned to drive the stock GT-R it like Suzuki-san
How is your new car going? Have you started modding it yet?
