My GT-R has finally passed an engineers certificate. The car is now “legal” and I can drive it on the roads without being overly paranoid about being defected.
With the stock airbox back in the car and a new quiet Fujitsubo exhaust I’ve passed emissions. I’ve taken the roll cage out and the carpets are back in too. I now have to go to a blue-slip station with the certificate and from there I can take the new blue-slip to the RTA and I’m all set.
New boost controller running 1.3bar now (was on 1.4 before).
In comparison to the last tune the curve is a lot less aggressive. Indy says the stock airbox is to blame, it just can’t suck in enough air quick enough.
