ok in road and track they had a blurb about the Nismo S-Tune and upcoming R and Z tune but then regretted to say it was only available in Japan and its a shame b/c all that only costs 5 grand to upgrade. First of all, I thought it was much more than that and second of all, they made no mention of Nismo coming to the US? Wouldn't they have printed that or Nismo have told them that? Hmm...

 

Don't worry, all the S-Tune parts Sam tested are coming to the US. He was not properly informed.

 

And what will the R and Z tune be???

 

it said the R-tune is specifically for track and the Z-tune is even further modified for track

 

correct...
