For those who wondered how the 0-60 restriction removal works; got an email from Hypertech:
The VVEL is used primarily to eliminate pumping losses at part throttle. All VVEL and throttling methods are tossed out the window when it’s time for maximum power. At full throttle, the cams snap back to full duration and lift. This is where the throttle control system steps in. This system is used to deliver a certain driving style and engine output. Think of it this way. The same engine (essentially) comes in the 370Z and the G37 Sedan. There are only minor differences mechanically, but the cars drive differently. That’s due to the throttle control system primarily. In both cars though, if the driver puts the pedal to the floor at low speeds, the throttle doesn’t open fully until higher speeds. We fix this to offer maximum performance.
What Hypertech has done is remap the power output of the engine at lower speeds. Nissan delivers the cars to their dealerships and they drive one way. We remap the engine parameters, and they drive another way; hopefully the way our customers like them to. The driving difference is so great that we decided to offer the option to swap between Nissan’s and Hypertech’s driving style. This is offered in the “0-60mph Throttle Restriction” option. For performance it’s great, but not everyone who has a G37 or 370Z may like the dramatic change, so that was our reasoning for the option. The wording for the option explains the change very simply. In reality there are changes to the performance and throttle restriction at all driving speeds and pedal/throttle positions.
You should notice a drop in 0-60 times with the Hypertech tuning. The additional torque gained across the RPM band will accelerate the vehicle quicker, along with the removal of the throttle restriction, and the takeoff will be absolutely better with our tuning (It will annihilate the tires!).
We don’t have any track data to show an increase in vehicle speed. Our local track that we test at, Memphis Motorsports Park, was permanetly closed down last year before we were able to test the tuning. We do have dyno measured HP and torque gains.

I skimmed this entire thread and didn't see any reason why someone would pick this over the Cobb Access Port. Are there any differences in features, ability to do custom tunes, throttle opening capability, etc? Please post up a side by side of features if you know them.
Thanks!
Thanks!

For those with Hypertech, how much has the throttle response improved? I understand it fixes the 0-60 WOT issue, but does that translate into more aggressive acceleration from a stop? Is the hesitation when pressing the accelerator from a stop gone?
My 2007 G35 took off like a rocket and although some felt it was overly sensitive, I loved it. My 2010 G37 feels slow in comparison and if the Hypertech fixes that laggy throttle from a stop then I would be very happy.
