This is my second Sprint Booster (Thanks Jason!) My first was a V2 SB that had 3 settings, off, street and race. Like another post here, I had mine on a tuned Mini Cooper with a 6 speed manual. The stock throttle response was crazy slow on the Mini especially when comparing it to the last "wired" throttle control car I had. It seriously transformed the feel and response in that vehicle making shifting much smoother and making quick acceleration feel as it should. The V3 SB takes a major chunk out of the lethargic throttle response and the ability to have more adjustability on the newer version is really nice. I've been tweaking it here and there but for now I've kept it on the green 7 setting. I agree it's pricey, but since this is my daily driver, the SB is going to be the only modification I do to the engine since it really helps the driveability.
I was on the fence for months reading threads and researching as much as I could about this mod before I got off the fence. This was mainly because I never owned a drive by wire vehicle before personally. I was also afraid this was just another one of those performance chips that all over eBay that are nothing more than a resistor or something that does very little in the way of performance other than some that just advance timing a bit. This device completely changed the feel of my driving experience in this car, which had plenty of power, but just didn't feel as fast as it should. Now, every time I get in it, I'm happy with the performance and it now feels like it should. The cool thing is that you can tailor the throttle response to suit your driving style. I tried several settings, one at a time, and left them for a couple of days to evaluate before moving on until I found the sweet spot for me. For me personally, it was the best money I've spent on any mod so far, other than maybe the exhaust, which also added greatly to the driving experience.
This was the missing link that brought everything else together, and I'm sure most just assume (like I did initially) that it's just a snake oil product. I like it so much that if it ever broke, I'd HAVE TO replace it immediately, lol!
All I can say is wow!
I have a turbo G. I was always disappointed in the power under 3k rpm.
This car (LP560) doesn’t have particularly high torque numbers stock so I figured it is what it is. It always felt sluggish at low RPMs. I couldn’t figure out why but just attributed it to turbo lag. I kept thinking to myself, “this must be a very underwhelming car without the turbos.” Now that I’ve installed the sprint booster the car completely comes alive at low RPMs. It’s remarkable how much more torquey it feels.
But here’s the real benefit: it is so much easier to leave from a standstill. As a MT fan I was not sure I’d like an egear car. I have to say it is really a good system once under way. This car is a handful with all the power and speed so having both hands in the wheel is nice. BUT starting from a stop sucked big time. I have a racing clutch that is full of chatter and is grabby. Basically leaving from the start line it either looks like I’m trying to race everybody (take off like a jerk) or that I can’t figure out how to drive my car. There was no ability to ease into it. I put the sprint booster on red 6 and it totally smoothed out the transition from stop to rolling. Unreal.
