Huge power for RWD Skyline, almost too much lol. But yeah, might as well take advantage of the huge power and get Trent to make it a conservative tune for longevity! Just be careful with third gear...albeit the most fun, they are also the most susceptible to instant gearbox destruction in GTS-T and GTR boxes (especially). What rubber are you running?
Also, I believe you owe me a post-tune ride in your vehicle, Tony.
