Fact: Sprint Booster remaps throttle response to make it more sensitive.

Fact: You can do the same thing by mashing your gas pedal.

Please point to where myself or anyone else in this thread implied that this adds horsepower. Are the only valuable performance mods related to power?

Is the DINAN transmission software a waste also?

But before you respond - please, let me know if you have ever actually used sprint booster...I'm dying to find out if your opinions have any real value.

Although I got quite the chuckle from your rejoinder, I couldn't help but feel this is like a school yard fight. How about if everyone agrees to play nicely and recognize each of us perform mods to suit our own tastes and preferences, whether they be aesthetic, performance, or just plain finickiness?

As much as I don't blame people to be skeptical, no where does this product claim to add any HP.

I can honestly say that I REALLY like what this did to my throttle and I had a problem with how slow my car downshifted before I even knew this existed.

I do find it a little funny that people get a lot of s**t for buying this snake oil, but 80% of anyone who races amateur on a sport bike puts a 1/4 turn throttle on their bike. 100% of MOTO GP and WSB bikes have them stock....Same exact concept.

I think the reason some people diss the Sprintbooster (and I am among them, to be fair) is because of the claims that are frequently made. Sprintbooster themselves cultivate a certain amount of confusion around what this product will do, and I think they do that very intentionally. If we bring it back to a discussion around altering the throttle pedal gain, then there is no debate, and no flaming. If people are happier with the pedal response they get with the Sprintbooster installed, then they should use it IMO.

Your first sentence states that you have done quite a bit to increase hp, and nothing has had as much of an effect as this. That seems to infer that the Sprintbooster can somehow increase hp, when we both know that it can't. I think you probably meant that nothing has had as much of an effect on your driving enjoyment, or something similar, and that is fair. However, not all readers make that distinction.

The Sprintbooster website says that it doesn't increase hp (I suspect they added that disclaimer due to pushback) but it also uses the phrase "enhance the driving experience by providing increased acceleration time (eliminating delay)" Sure it can eliminate delay. But exactly what is 'increased acceleration time'? Do they mean reduced acceleration time (ie, reduced lag)? Some people would read their claim as implying increased acceleration, which is patently untrue. They also use the quote "delivers more impressive off the line performance". Really? that 0.1 second reduction in delay improves performance? I guess you could say it does, by 0.1 second, but really, it is misleading. It improves throttle performance, not engine performance, might be more accurate. With the Sprintbooster, according to the manufacturer, there is no difference in the first 3/8 of pedal travel, and then the ramp is increased, so that full throttle is achieved at 3/4 of stock pedal travel. That's it. If that makes it feel better, by all means. I have no doubt that some people would prefer that pedal action. But every time that they sneak in a phrase about impressive performance, or increased acceleration, they lose me. I just think that they are acting exactly like a snake-oil vendor, not that the product is itself snake-oil for its intended use.

When sedate-driver reactivated this thread, he noted that he was at risk of flaming. However, he made it very clear that he didn't see this as a performance mod, simply as a mod to pedal response. What happened? No flaming.

Glad you like your Sprintbooster.

Good comment, you posted while I was writing so I didn't see it until after.

I have an M3 which has a sport button as stock. Does the same stupid thing as a sprint booster and I don't use it as I prefer to retain more control, as indeed most M3 drivers do.

You love your sprint booster. Enjoy it!!!

BTW, I have a modulator that plugs in between the fuel gauge. It makes it more sensitive, so you can see how many drops of gas you have. Cost is $100 but you can have it for $200

Chill out dude

Even when one goes to a five star restaurant, we still add salt and pepper to taste. Same goes for modifying vehicles, it all to personal preference and taste.

I was merely pointing out fact before a certain someone chimes in with an attitude...and since this is a forum I thought I would point out fact.

BTW I have a street bike also. The throttle modulation done there is as it is not as easy to "mash the throttle" on a bike as it is with a vehicle. Think about it!!!

I apologize if I started any unnecessary commotion!

Noodles, you gotta at least tell me...have you used this product?

I just purchased a sprint booster today!!! Size 10.5 and feel awesome!! It helps me push the pedal down much faster than before

Thanks.

On your earlier post about SB marketing, I too thought it a bit misleading but quite frankly didn't parse it as thoroughly as you did. Nonetheless, I was sufficiently disgruntled with the X5's throttle lag to try just about anything, even snake oil!

I'm what you might call a reluctant X5 owner. With the kids off to school, my wife wanted to downsize so we got her a 335 xdrive and I got her hand me down. I never liked driving it (nor my son for that matter) but, being her car, never made an issue of it either. The combination of throttle lag and transmission lurch drove me bonkers. I even had it on the selling block for a while but our local market is flooded with E53's so I didn't think I'd get what I thought it would be worth for me to keep.

Now that I've installed the SB, I can say it has brought the fun back into driving this thing. I have a more predictable throttle response and the tranny lurch is pretty much eliminated. I don't know if the SB website voltage output graph is accurate for every car or is a simple, representative sample but it seems the faster low end response made all the difference for me. I would imagine there are those who prefer to mash their foot to the metal and for them the SB would be a waste of money because they won't see any difference. For me, this $300 "tweak" was well worth it for driving enjoyment.

I'm sure you didn't mean it but your choice of words isn't conducive to calm discussion. I'd suggest you stay away from inflammatory words like "stupid thing." It's way to easy to misunderstand and think you were calling into question the other member's intelligence and I'm sure you didn't mean to do that.

On facts, you will also need to understand that it is only natural to discount your assertions if you haven't tried the product. Your first assertion that it becomes more sensitive because it remaps the throttle response is correct, is a fact, and is what SB claims. Your second assertion that you can achieve the same thing by mashing your pedal to the floor is no longer a fact. It contradicts your first assertion because remapping the throttle response clearly will produce a different result no matter how much or little you mash it. Mashing the pedal may get you to the same signal strength and, if you have a very finely modulated foot, even at about the same time as the SB but what you won't get is the response linearity. Whether linearity is important to you or not is a matter of subjectivity and is no longer a fact.

Lastly, many of us would appreciate it if you would stop referring to a higher authority as if that would substantiate your claim. I have an M3 stories really don't add much to the discussion since the differences between vehicles are just too great to make meaningful comparisons, at least at the esoteric level of these discussions. I also have a Sport button on my M car and can tell you the overall vehicle response is markedly different to a SB with an autotranny. Speaking of which, I actually wish my X5 was a manual like what the Europeans have. I think they "dumbed" it down for the North American market. Whoops...my bad - shouldn't have used dumb; I meant manuals wouldn't sell here.

I hope these observations help you understand the other members' response.
