I'm with this crowd.I love mine too. It's definitely not the same as just stomping on the gas. It's almost instantaneous that will snap your head backward. I don't doubt if this will improve your 60-foot time.

 

there's also one called Sprint Booster that has some cool features like pedal lockout and valet mode that can cut max throttle by 55-75%

 

I am considering Sprint Booster as I do research for my RCF over the Christmas holidays as something I could install in the garage. I said above, I am happy with the mode I primarily use, which is sport+/manual throttle response. It is very sharp and have no complaints so I did not feel the need of doing anything more t it. Why did I change my mind? Because I just want to as an experiment and out of curiosity. LOL

I have been watching a lot of videos and Sprint Booster seems to be the best option. It is very straight forward to install (does not require calibration), the control module is tiny and can be disconnected after selecting settings or turning it off to make it look like OEM and also the reviews seem to be the best as far as quality goes. Also, it seems to memorize the last settings you choose even after a restart.

I might get asked about RR racing tune. Eventually, I might get RR racing tune, but right now I am not ready. I have seen videos of people having misfires, CEL, limp mode issues, risk of frying the ECU etc. Granted they were IS350/RC350s, but still I just feel having a more savage throttle response is a simpler and safer option at this stage. From the test data I have seen on one of the forums, it does improves the 60 foot (and hence 0-60 mph) so it seems to check all of the boxes for me.

 

I have a pedal commander, and it made such an extreme difference, I rarely drive in sport or sport+ mode around town. Wasn’t concerned about actual improvement in 0-60 time, just hated the pedal lag/needing to slam down the throttle for a response. I did come from driving a 500+HP SC’d 5.0 mustang...so I may have been a little spoiled with throttle response

 

I really love how it behaves in sport+/manual and how snappy it is with full exhaust and stage 2 cold air intake. I can easily break the tail loose in sport+, but like I said above I am really doing it out of curiosity. Majority of people say, it amplifies the experience so I am going to just do it as an experimentation with little to no expectations. I will go with the sprint booster since that seems to be the most compelling based on the reasons I gave above.

 

Sport mode is where it's at, Sport+ is a little aggressive for normal diving. Don't understand how someone can complain about throttle response but only ever drive in normal or eco.

Looking at throttle maps in tuning software and there's a pretty big difference between eco, normal and sport modes. I'll get a screenshot next time I'm looking. Basically eco and normal limit throttle in relation to accelerator, with normal limited to 66% until the last 90% of pedal travel. Eco was something like 40%. Sport is fairly linear. Sport+ looks a bit like those pedal commander maps, where it's at 90% at only 75% pedal travel. Basically use the other driving modes before thinking you need some aftermarket device.

I pretty much drive in Sport 90% of the time. Sport+ being used in track days or mountain runs.

 

I ordered the Sprint Booster today - will let you know how it goes.

 

I've put my wife's NX in eco mode one and it was a dog, straight up horrible. I can't fathom why anyone would ever drive in that mode because the response was so slow. On top of that if there were ever a situation and you need to put your foot down, Eco is so laggy I can't image that turning out for the better if you need to get out of the way or do an evasive maneuver .

I noticed that in our drive settings if you push the "Normal" mode again it goes to "Custom".. I have my Custom set up for Power on the power train and comfort on the suspension. Figured this would be better for "normal driving" and it would in theory put the acceleration better than "normal mode" but not as high as sport/+?





I'd say honestly though for when I drive the car it goes straight in to Sport + then the highest when I want to get on it. It's just too fun not to have quick throttle response..lol. I'm always hesitant to use a device like mentioned.. I don't want to be stranded some where because something conflicted or fried another component. Ideally I wish we didn't have drive modes or it was something that could be 100% customizable. (I like bmw's where you can get into more detail of suspension settings, power train, shifting) IE: I want the drive mode to be my right foot. If I floor it, I want to go. If I granny the pedal I don't want to go...etc. Things have gotten gimmicky in the last several years with cars.

I use Sport+ for all of those reasons you mentioned above. It gives the most exciting experience. Also, remember it does not just change throttle mapping. It also changes other parameters as well. The VGRS goes into a more heavier/faster setting and the brakes are boosted a little more etc. Still, I think something like Sprint Booster is worth a try as it will make the car feel more "front loaded" in terms of power delivery. It is fairly cheap so worth at least trying. I agree the sport+ throttle mapping is already more than enough considering my head hit the headrest a few times while slowing down for a right turning and then suddenly tipping into the throttle.

:Let me know how it goes. I have 3 different mods I am contemplating and which one to get first. If boxing day sales are great, I might pick one up as well. Let me know how the installation goes..

Yeah, same here. Interestingly, your 2020 has a different throttle mapping in Sport+ than the 2015 - 2019. Apparently, I saw the graph overlay and the 2020 has less initial "bite", but more consistent response while the 2015 - 2019 has a big spike in power delivery in sport+ mode in the first few inches of the throttle movement. From all of my research, devices like Sprint Booster are pretty safe. Never seen any case of someone being stranded or the throttle behaving erratically. It is a very simply device that simply changes the signals being sent by TPS and makes them more aggressive as far as opening and closing of the throttle body. You can also turn it off and it restores the OEM connection (SprintBooster).

 

I would honestly use Sport+ more if it shifted above 6th gear on the interstate. Looks like I might just need to get a newer model that has that Custom setting.

 

Mine gets to 8th in sport+. I think this has been discussed before. I have seen it myself under certain circumstances it does not let you shift above 6th, but I never have been able to figure out when. Is it when the engine is not fully warmed up? Is it the load due to gradient? (uphill). Not sure. But, I can get to 8th no problems when the circumstances are right in sport+/manual.

 

Which other two mods are you thinking about Rolla?

 

Lightweight battery, carbon fiber mirrors, FIGS solid control arm bushings and also the Sprint booster. All of these are on my list. Just trying to see which order in which to purchase them.

 

So, I threw in the towel and ended up ordering Sprint Booster v3 as well. It would be the first in my winter upgrades. Carbon fiber mirrors will be next.

 

I installed mine yesterday. I like it. I know it doesn’t add power but the car is much more responsive. I had it on race 9. I think I need to back it down. Car kept breaking traction. Lol
