Sprint Booster Installed:throttle Lag Gone!!!
#61
Finally installed it! took every bit of 2 minutes, noticed great throttle response once I'am up am moving around thirty five - forty, seems to take second gear all the way to red line taking its time, quicker without it the plug adapter from a dead roll??? Could this be from the ECU flash?? Fabspeed? almost crawls off the line, sounds like your staying in 1st gear in a forty mile an hour zone?? anybody else experience this?? great once your moving.
It is great once I get rolling, I even tried the tiptronic in 1st, before I used to be on the other side of the intersection before anybody else even started rolling. Its great and very responsive once rolling? I'm thinking the Fabspeed tune? I might call Fabspeed tomorrow and ask?
Not sure what you are trying to say about it affecting the throttle response at redline, because the Sprint Booster only effects the throttle curve until about 3/4 of the way through the rev range, then it reverts to stock.

I'm not sure why but it did?? I talked to GMP yesterday only possible conclusion may be defective? I returning today's mail and will love to try again with a new one once it is shipped to me, as soon as I removed it the truck ran the exact way before I plugged it in?? The best way to describe the problem was that it seemed like the transmission was in low range (on four wheel drive other vehicles you have a high and low range tranfer case setting, this seemd like it was in low range, reving very slowly but the engined sounded like I should be going 10 times faster and went all the way to red line?? Once past 2nd gear it was fine and I really could feel the booster responce?? I am willing to try another one?
The Sprint Booster should definitely be improving your response right off the line, as well as once you are moving. If it's not then you may have another issue that is coming into play.

You should have no issues with the warranty. And there's no need to have the dealer install it. It's really easy, and we have a how-to posted here: https://www.6speedonline.com/forums/...r-install.html

2nd time is a charm!
Thanks Matt for shipping me another Sprint Booster, took few minutes to install and works great!, incredible how touchy the pedal is, love the response time, It's a damn shame I now have to try one on my 996TT!! Let me know if you can test the one I sent back, curious if it was defective or on my end from incorrect install???? Thanks again!! If it works the same way as the CTT when I install it on my 996TT I may have to install one on my 99' 996???? when will it end........

Question:
I don't have the throttle lag that some others have reported in this thread!
Therefore, would there be any kind of benefit for me to install this device?
Also, does it use noticeably more fuel over stock?

I will test one in the day or two, 06 Cayenne S, I will let you know.

Go out and rev your the car a few times, paying close attention to when the tach actually responds to throttle input, and how far your foot has to move to make it rev. It's not impossible for the lag to vary from Cayenne to Cayenne, but I'd be VERY surprised if you didn't have at least some delay. It's present on nearly all the drive-by-wire cars I've ever driven.

Response to GMP performance.
I just tested my completely stock 04 Cayenne S for throttle response under various conditions.
From a dead start or even at any speed, pushing the throttle 1/16 to 3/4 rapidly or slowly does not produce a lag of any kind (instant neck snapping response).
At wide open throttle there is a delay of about a second or so just before the car starts to pull very strongly. This delay is more noticeable at highway speeds.
It feels to me that this delay is caused by the transmission trying to find the proper gear before it allows more power to be applied by the computer.
In this case, will your device make any real difference other then just exaggerating the pedal travel?

You sure you're stock? My '05 Turbo doesn't even give me a 'neck snapping' response.

What the Sprint Booster does is speed up the signal that is sent response to your throttle input. Once it has been received, the Sprint Booster's job is done. And yes, this does exaggerate the throttle travel, but this translates into quicker reaction by the computer.
If you'd like to test one out for yourself, we've been sending these out with a 30-day money-back guarantee. The only ones we've had returned have been switching to a more aggressive/less aggressive version.
