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.
