I've done quite a bit to increase HP on my 4.4i and nothing has had as noticeable of a difference as this.
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 shit 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. |

Save yourself some money and just mash your gas pedal.

One could say the same about your smoke reflectors, LED License plate bulbs and Aero kit. I can promise you this, sprint booster will make more of a noticeable difference to your car than any modification you have made so far.

Fact: Sprint Booster remaps throttle response to make it more sensitive. Fact: You can do the same thing by mashing your gas pedal.

Free Online Reading Lessons from MontessoriHome.com 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. |

![]() 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

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.
