also what octane is the gtr using? i had to bring in my gtr to the dealer to get a retune for 91 octane , my car had a significant hp loss due to the ecu being programed for 93 octane, after the dealer reflash my car was a complete different animal. ive raced m5s on the highway and ran away faster than you did in your video from it.
