I just installed one on 2010 7AT Roadster, and it works as advertised, I have no intention of sending it back. The lag is practically zero now, the car always seems to be in the right gear, and it just feels faster. I know it's not, but you'll feel like it is. This is how the car should always have felt IMHO. Now much more fun to drive.

Oh, one more thing, the install is as easy as it says.

Do I think it's a over priced, well, yes. But, you won't regret it once you get it.

I just ordered mine. After reading the reviews on 6speedonline I had to see for myself. I'm sure this will restore the throttle response I've been missing from my 350Z. I'll post my review when I get it.

I have no wiring diagramm of the sprint booster. But to do this he has to modify both different resistors characteristic lines of the accelerator pedal. There are to resitor lines because of safety. Can you imagine the problem if the cheap c++ microcontroller A/D - D/A sampler circuit ist doing something wrong because of EMI from a mobile phone. You got an SMS and the car is ignoring the red light :-(

You can also hit the pedal harder to let the wheels spin :-)

Flooring it is flooring it, the sprint booster does not change that, it does not change engine characteristics only throttle input percentage.

To fix the lag you need a tune.

Hopefully my dealer is getting to the bottom of this. I don't see how some of this lag can be attributed to DBW especially after several miles of driving the car with at least 75-80F ambient. The 350Z never had this issue.

The tech I drove with confirmed the lag and says it feels like a lean condition. Unfortunately it was cold (< 70F) so it was a hit or miss, so hopefully it's warmer tomorrow for another test drive with the tech to gather more data so he can open up a case with Nissan.

I thought about the SB as well, but I don't think it'll fix the issues described.

Ok, so the SB increases throttle input percentage. So then if you have it in race mode you will attain full throttle at about 75% of throttle travel. Now, if you mash the throttle down in this mode will it not reach WOT in less time? Assuming we are pressing the throttle down equally as quick in each case, it would take longer to achieve WOT in the stock setting. If this stands to reason then improved throttle response would be the result. Would it not?
