Since the GTR first launched, each time Nissan have upped the power of the GTR from the MY09 GTR to the Nismo GTR, the increase from BHP has gone from 480hp to 590hp (Nismo), yet the torque has gone from 430 to 490 (Nismo).
My question is, if tuners say the can "safely" cap the torque at 600, then why hasn't Nissan tuned the Nismo with around 550-600 torques? I'm aware they need to use a Tune/Map for all climates etc but if we compare the figures to say an Ecutek Stage 1
Nismo: 591/490
Ecutec Stage 1 GTR 570/550
Seems like Nissan isn't too keen on tuning in a lot more Torque as the BHP goes up.
Thoughts?
