Dude, I have the booster now, and I'm relaying my experience here. You can tell me ten times over to step on the pedal faster, and it won't change my perception of this experience. 
Once again, I'll remind you of that simple lesson:

You know I respect your opinion, 2slow. A whole lot, actually. However, I already answered my "Is it a scam?" question with:
All that aside, what's wrong with the illusion of performance? By my way of thinking, it's all about the driving experience. I'll prioritize having fun over measured speed any day. Quarter mile times are irrelevant. Enjoying the acceleration experience and the connection between car and driver... that's what matters. (That's why I drive a 6MT.)

According to knight_yyz, retailers are obligated to let you try before you buy. Have you tried it yet?All that aside, what's wrong with the illusion of performance?

Yes, but not in a Maxima. My experience stated so as to not offend:
I've used one with a Chrysler Crossfire, and it does exactly what was previously stated; increases pedal position sensor feedback to increase the throttle position.
While it 'took-up' the lag quite well, it caused other driveability issues for which it was removed and now resides on a shelf. It made small throttle applications, or variations of, very sensitive which affected ability to smoothly start the vehicle and modulate part throttle applications (greater than 50%). These experiences caused us to remove the sprint booster, which made the vehicle much easier to drive (auto-cross).
I don't think there is enough throttle lag in the VQ to warrant this, especially for the price.
More street cred:

The only real way to get your opinion aligned with mine would be for you to drive my car, with and without the booster. If you were anywhere nearby, I'd happily make that challenge available to you, 2slow.
Until then, you'll just have to accept my opinion at face value. Without empirical evidence on how it changes the driving experience in my Maxima, you can certainly be skeptical, but you can't deny my experience. Remember, I was just as skeptical in Perkman's Sprint Booster thread back in December '09. In fact, I directly said, "It feels like snake oil." I never would have tried this thing on my own, if it weren't already installed when I came back from test-driving Markus' TE. But boy am I glad I did.
Perception is personal. 2slow, this thing makes driving my car a whole lot more fun.

some cheap eco cars Ive driven have this kinda program stock for example Honda Civic.
when I drove the Civic at low speed, the throttle control was very sensitive, just a little bit throttle the car would jump forward giving you an illusion the car has a lot of power but when you really punch it, nothing really happens.
on a maxima, the stock setting is a bit like the bmw 5 series I drove, very gentle and smooth when going slowly, when you punch it, the power becomes a flood.

Here's the problem:
Your perception will likely not be the same as mine, even if all other variables are controlled.
I've used this product on a vehicle which has a real problem with throttle 'lag', and felt the marginal benefit (different feeling) was out-weighed by the negative (increased sensitivity). Especially since the percieved torque 'increase' can also be accomplished with a 'deeper' pedal depression.
This is becoming more common since it's soo easy for a manufacturer; usually labeled as push-button sport mode. Another (not so cheap) example is the turbo-charged Mini Cooper S, and I think I recall it on other BMWs, but it has been a while.

I will agree that dyno's are not everything (but usually are when speaking of engine performance), and will re-assert my primary negative was related to driveability (due to increased sensitivity) which decreased fun. Consequently, the $ per fun was off the chart horrible (<0) with a negative fun quotient.
Again, just my $0.02.

It's working out fantastic for me with my Maxima.

It's kind of like the 7th gen CVT. Don't get me wrong, I love my clutch pedal. But that 7th gen CVT is a blast to drive. There are so many little nuances available for you to become attuned to, ways that connect you to the driving experience. You're "shifting", but there are no gears, and it doesn't really matter because it's a lot of fun.
Know what I mean?

The only way to prove this is to go to a dealer and take a test drive. Can't prove it on paper, can't prove it on the internet. Geeze, the darn thing won an award at SEMA this year and you guys are still so negative. You're all trying to quantify the thing into horsepower gains, and how much faster does it make the car go. That isn't the point. Or flooring the car gives you the same result. No it doesn't. If you don't believe it, hit a dealer and ask for a test drive. What have you got to lose? Worst that can happen is that you will find out you are wrong.

So many variables, all mixed in with the ineffable experience of making the car (my car) more fun to drive. I'm just putting this out there, guys. Do what you will with it in whatever way sits well with your values and your budget.

A larger MAF housing necessitates active tuning, right?
In which case, you're correct, Nmex. That's not where I want to go. I'm in my happy place right now with the Maxima.

actually, you can. because what it does, even according to themselves, is replace the current pedal position reading with one of a further position. it does not do anything you cant do with the pedal, the voltages all remain withing the normal range of pedal position, so if done correctly you could identically replicate this effect with just your foot

from sprint booster site
"Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street.
Sprint Booster simply modifies the throttle signal between the accelerator pedal and the throttle body. Big deal right? Keep in mind, this is the same concept as the 'throttle pulley' modification on cable based throttle systems - which was very popular in it's time. It doesn't add horsepower, but makes the throttle more sensitive and makes the car 'feel' faster."

i dont have any intention of talking you out of your enjoyment for it cause honestly, i dont care if you love this thing, i just post in hopes that if other people read this thread understand that it doesnt do anything you cant do yourself for free (minus the hit to your wallet for gas)
truth be told, it would **** me off to no end if giving 3/4 pedal gave full throttle in my car, cause when youre going fast, tearing up canyons or whatever you enjoy, if youre driving hard 3/4 throttle and full throttle cant be used interchangeably if you wish to keep traction and stay on the road. if you know your car and are good at driving it, that is throttle sensitivity you cant live without

But people don't have to waste money. They can try it for free and form their own opinion instead of listening to conjecture from people who have not even tried the thing. And I really don't car about your opinion of it either. I just post because I want to educate some people who want to get rid of throttle lag.
And until you actually get off your butt, go out and try the thing, anything you say is an opinion not a fact. If you want to state a fact, try it out then come back and say it is a waste of time and money.
No one said this added any horsepower. It eliminates throttle lag, and mashing the pedal to the floor does not eliminate throttle lag. Reflashing the ecu like technosquare, reduces throttle lag, and the spring booster eliminates throttle lag. If you push the pedal halfway to the floor and it takes 10 seconds to respond, then pushing the pedal all the way to the floor will still take 10 seconds to respond.

this is THE most horrendous festival of hyperbole ive seen in a while. maybe your car was f'd up, but I never have had that trouble. when I pushed the throttle, before the f-spec, I never had any trouble with throttle lag. Not to mention this doesnt actually solve throttle lag unless you actually do take 10s to depress the pedal, then it would get you to 100% throttle in only 7.5s vs 10s, according to their data

What is this mysterious lag everyone keeps talking about? Is it the .05 seconds it takes to press the petal to 50% throttle position and the .05 seconds it takes for the signal to be processed? I don't see how this thing could do anything but eliminate that small amount of time by starting at like 40% throttle when you first step on the petal. It certainly cant make the car process the signal faster.
Or am I missing something? If you just decided every time you hit the gas to drop it to 40% throttle position instead of 10% isn't that the same thing? If it isn't why not?
Knight can you link to a website that shows dealers for the product to get it test driven the debate has got me curious.
