Congratulations DS team!
I just managed to install today the full upgrade from stage 3 to stage 4 including the turbo X map (with the help of the guys from Exelixis motorsport Romania - who are actually specialized on Nissan Skyline GT-R's

).
What a difference!!!! The car runs very smooth and extremely powerful as if it was factory tuned

. I am so glad that I have fitted also the Quaife diff because I can't imagine how the standard diff could ever cope with such power!
I would be interested to hear opinions of other users who are actually running the new stage 4 with turbo X.
Thanks.
I was running before a Superchips stage 3 at 310 hp but this is definitely a whole new level.
Good job
