"Do the reprogram."
"Come on, for the sake of investigative journalism?"
"Don't do it. You all are responsible enough not to ruin this car." ( Says you.)
"I vote no.
Use the car the way you bought it."
We went back and forth internally for about 5 minutes on this one. On the one hand, launch control is awesome, and with the GT-R it'll dig four troughs in the asphalt before shifting to 2nd and hitting 60 in under four seconds. It's a parlour trick we just can't get enough of.
But then there's every other reason we should get the transmission "recalibrated:" It's what most owners (probably) will do. We'll be less likely to blow up our GT-R. You get the idea.
The debate came to an end on Friday when we got the call from our local Nissan dealer that they had the update. This is despite the Letter to Dealers we published that said GT-R owners would be notified on the 16th. We jumped at the chance. It would allow us to get new performance numbers and let other owners know what to expect. It was a no-brainer at that point.
Turns out the release was available well before this (as some people have already run some quick times post-mod), but then pulled back and re-released. We're not sure what they did in that downtime, but owners who had it done prior to last Friday might want to check back with their dealership. We have the final release.
Our GT-R took the new tune without an issue and was in the care of Nissan of Santa Monica for about two hours. Ours was the first customer car re(de?)tuned.
The new transmission calibration came in lockstep with the new tires we had ordered from Stokes Tire Pros here in Santa Monica. A new set of Bridgestone Potenza RE070R size 255/40ZR20 showed up Saturday morning and were mounted that same day. The total cost was $853.90. The manual says that all four tires may need to be replaced at any time. Ours did not. The rears are still in great shape.
Stay tuned for post-recalibration test numbers.
