I completely agree that WOT is WOT. Thats understandable. My point is that the Sprint Boosters lag removal and quicker response will get you up there alot quicker. Therefore, the one WITH it will most likely outrun the competitor. This ofcourse having 2 stock 370z with the exception of one carring a sprint booster. I don't know why so many try to discredit what this little device does. It really is the best bang for your buck. HANDS DOWN.

Considering it costs half of an Uprev tune that accomplishes pretty much the same thing and a lot of other stuff as well, I'd argue the exact opposite.

Edit now that I'm not typing on my phone- Of course you'll feel a noticable difference with the Sprint Booster. I've never argued that fact. Since you're compressing 100% of the throttle opening into the first 70% of pedal travel, it'll feel much better. My point is that all it's doing is moving you into a different area of the stock throttle tables faster. That's all it can do. It has no access to the ECU. The values in the stock tables suck. Why not just use Uprev to adjust the values in the tables? You'll get the feel you're looking for, but preserve the shape of the throttle curve and not hit a dead spot between 70% and 100% pedal travel.

There is already various testimonies on this forum from people with uprev tunes that have stated their uprev tune did NOT have such a big impact on throttle lag and responsivemes as the sprint booster did. Now, their either all lying or all paid 600 dollars for bad tunes. Ill be needing a tune soon when my headers come in and according to countless testimonies across multiple forums and various owners from audi, BMW, chrysler, nissan, suburu, etc etc... it seems to keep everyone happy. I think its pretty much speaks for it self. Its been well worth every single penny spent on. It still catches me off guard as a matter of fact. Everybody seems to love what it does. Have you tried this device? I'm just wondering.

Oh and their is a 09 GTR bieng sold on cars.com for 55k and 25, 000 miles. Lol

Like I said in my last post they did not get the throttle tables tuned they only got a/f,idle speed,timing stuff like that most tuners don't know how to tune the throttle maps if they did you wouldn't need the booster.

It's not a given that a tuner is going to spend a lot of time dialing in the throttle tables. Most likely you'll have to make sure they know it's a priority for you. It's not a knock on the tuners, but the vast majority of them are spending an hour, maybe two dialing in the overall tune and not spending a great deal of time on the throttle tables.

There's a lot of people who have gotten their throttle dialed in very well using Uprev. You could take one of the throttle tables from there and have your tuner do something like that.

If the Sprint Booster costs $300 and only deals with artificially compressing the throttle signal vs. $600 for a full tune that adds power, adjusts the throttle tables, lets you control the fan temps, etc, I just don't see the value in the Spring Booster. You do. I'm glad you feel that your money was well spent. At the end of the day that's all that's important. I'd personally rather change the tables themselves than use a device that forces the throttle to another cell on the map.

I ran into that thread before I bought the sprint booster. Even though it does improve throttle response it seems to still cause trouble down the road as updates become available. Would this be another 300-600 dollars to adjust? A tune is well worth the money and at some points required.

Not everybody needs an all out tune. Why pay 600 dollars for a stock z all because you simply want more responsiveness with no need what so ever to change the timing on fans when you can just settle for 280 and have one hell of a change.

Guess it just boils down to that persons specific sitiation. I will be getting an all out tune some time in the near future because Ill pretty much be required to. I think then more then half a thousand dollars are well worth it.

Since you're going to get a tune anyway, take one of the maps from the thread I linked with you. Have the tuner program that in. That way you can give us your impression of a good Uprev throttle table vs. the Sprint Booster.

Also, you're in TX. That's reason enough to tweak the OEM fan settings.

if you plan to get a tune anyways isnt best to just throw in the extra few hundred for uprev and get rid of the lag? would the sprintbooster and uprev combination improve it even more?

That's what we're trying to determine. If somebody takes a "known good" throttle table with them when they get tuned, it'll be easy to compare A vs B. Right now, we don't know who had much, if any, time spent on the throttle tables when they got tuned. It's not necessarily one of the things a tuner adjusts.

The stock fan has really never been an issue even in Texas. Arizona seems to take the cake. The sprint booster could be shut off at a tap of a button so it would be fairly simple to compare both once a GOOD tune on throttle response has been placed. There have been several people on here with both that claim the sprint booster does a better job but we don't know if their tune had emphasis on throttle lag and response.

Exactly. My wild *** guess is that with a properly adjusted throttle, the feeling will be fairly similar.

Is this the same as the spring booster? it says it only costs $59.50 vs $299 for the sprint booster

I have never tested that device. Seems like it does the same thing. I've never heard a testimony over that though. Youve might have found similar performance for a better bargain.

From Sprint Booster's web site

"• Sprint Booster does not increase Horsepower.

• Sprint Booster does not reduce your 0-60mph times.

• Sprint Booster DOES make your car 'FEEL' faster.

• Sprint Booster is not for everyone."

Draw your own conclusions. ;)

I wouldn't buy one, but no one can deny that a placebo effect is an effect none the less.....
