If you haven’t heard about Sprintbooster, then there is something wrong with you. If your on a local forum, regardless of what make or model. You must have heard about sprintbooster at least once. So what is it?
In a nutshell Sprintbooster can be described as the following.

“Sprint Booster is engineered to enhance the driving experience by providing improved acceleration by eliminating the delay inherent in drive-by-wire accelerator technology. This is accomplished by continuously measuring and converting the digital signal while providing the ECU (Electronic Control Module) with a new and altered signal for much quicker throttle response. The actual device contains electronic circuitry that is installed between the accelerator pedal and the ECU in vehicles equipped with electronic throttle control. Sprint Booster is an entirely new product that is environmentally correct. After installation there is absolutely no change in factory emissions and it is fully certified having obtained the demanding, German TUV approval for gas, diesel and hybrid vehicles.
Sprint Booster represents completely new technology, with no direct competitors. Enhances throttle response by increasing pedal input sensitivity, delivering more impressive off-the-line performance that drivers can genuinely feel. Installation is simple plug-n-play takes only a few minutes and rarely requires tools. Sprint Booster delivers instant response throughout the power band, making acceleration and merging with traffic a totally new and confidence inspiring experience. Shift points are redefined and maximized when paired with an automatic transmission. Standard, CVT and DSG transmission versions are also offered. Brand new for SEMA was a programmable version with Stage 1, Stage 2 and “Off” settings.
Johnston was careful to acknowledge that “while Sprint Booster won an award for ‘street performance’ it is the ability of Sprint Booster to eliminate throttle response delay that is consistently the most appreciated feature.”

Got all that? Well if you didnt let me put it to you this way. If you own a CVT Lancer, you know what I am talking about when I talk about the huge lag and lack of response when it comes to accelerating. You give it gas, and the Lancer always under estimates the amount of throttle your demanding. Its frustrating, you have to keep giving the car more and more and more gas before the frigging thing starts moving. Why you ask?
When programing the CVT transmission Mitsubishi designed it to keep fuel economy at the top of the list of objectives. Just short of 100% throttle, the CVT undermines you at almost every turn. It just doesnt get it. With sprintbooster in there. Its like a constant kick in the pants telling the Lancer you want to go and not mess around.
Dont own a CVT lancer, Maybe a Manual Lancer, or possible an SST equipped MR or Ralliart. Same problem of throttle lag exists. There is almost no way where you can hide from it. Factory throttle programing has lag. But dont take my word for it. Do a goggle search for yourself. Sprintbooster is on just about every car, and of the people that try it, almost 100% love it. Mean while, the people who never try it seem to be the most skeptical. I have to admit, I was a little unsure about trying it. But once I did, this mod quickly rose on my list of most have mods. I bought mine 2 years ago. And I must say, if i had to do my mods all over again. The Sprintbooster would probably be one of my first mods. Hands down. Before my exhaust upgrade or intake. Its that good. It drives like a totally different car.
The mod is so popular in the EVOSOUL circle of affiliates, almost every single one of us on the team have this mod. Once you try it, you wont want to turn it off or take it off. Effective later this month the EVOSOUL International group will likely distribute Sprintbooster as a vendor.
WHat is even better. Sprintbooster has a 30 day trial policy. You dont like it, you return it. and get your money back. No BS. www.sprintboosterusa.com . If you already have sprintbooster, make a comment on here. Or on the forums. I am curious to hear your feedback. Just look at Move-Over’s review.
Read one of the reviews for the product right here. If it makes sense to you Buy it.
