I agree. One of the best mods you can do.

Make sure you put things where they are not going to get obstructed (brake and accelerator) and you will be fine, I slid the box section underneath carpet off to left of brake and on the right pulled wires taught and tucked them into carpet behind accelerator

I have mine set at 5. I’ve found more advanced induced oversteer to quick on the track.

I like it -- except when I am barely touching the accelerator, like in a parking lot, or alley, or heavy traffic. Then it lurches. Anybody else experience this?

I liked mine, but it kept causing the car to go into limp mode after WOT blasts to redline. I ran it at 7. Now tha I have installed the Mamo ported throttle body it’s not really needed, but I might hook it up again and see if it’ll behave better at a 4 or 5 setting.

You have to learn how to "walk it out".. go EASY on the pedal!
Too many guys are heavy footed when they don't need to be, and jab the pedal... Just ease it and you'll be fine!

I liked the Vitesse but had the same observation. Annoyed me enough to remove it. Just for fun I tried the newest version of Sprintbooster. Seemed to have a little tip-in programmed in and do not have the same problem.

FWIW will provide some quantitative info. Was used to driving with MAX OEM throttle response in my 2014 Z51 none MRC C7 for 3 1/2 years. When I got my Grand Sport I was driving in Touring that was only slightly less stiff that my Z51 and in Sport it was stiffer. In Track it rattled your teeth in normal driving.!

Was able to set the Grand Sport steering response and NPP to always Sport or Track regardless of Drive Mode. However throttle response is not an available option setting. Even taking off was a bit of a PIA with my M7 from what I was used to in my 2014. Installed the Vitesse throttle controller and set at 4 or 5 matches what I had been used to for 3 1/2 years.

Vitesse says a setting of 5 is a linear response. I refer a setting of 9 (the Max) as "Boy Racer!"

Below are some curves.

I had an issue with the install solved by Vitesse. Could be an answer to those that tripped a CEL. Mine has been fine for over a year. This is a PDF of my install and minor install issue: http://netwelding.com/Throttle_Control.pdf




Note, although these curves are not directly from Vitesse, what I have observed matches these curves and what Vitesse says their device does.




In my 2014 only needed to drive in Sport Mode to have Max OEM throttle response. None isse for ride as my none MRC Z51. For my 2017 I would have to drive in Track Mode to get Max OEM throttle response.

I can see why folks like the throttle "feel" that a Vitesse device delivers. It leads one to perceive that it produces better throttle response, and if your definition of "better throttle response" is that you don't have to move your foot as much, I guess that's true. However, it is just a feel thing by changing throttle position. It's not delivering more power, and I just move my foot further and quicker when when I want more throttle.

It's analogous to the difference in steering feel between Tour, Sport, and Track modes. Steering performance is exactly the same, but the amount of power assist varies from heavy to light.

Have you tried one its doing more than you state, takes off like a rocket unlike before I added it - if you dont have one you will see, its a game changer

As others have stated its like pulling a trailer until you use Vitesse world of difference

As I said, this is when barely touching the accelerator. If I keep a constant very slight pressure on the pedal in first gear (say, easing through an alley), the car lunges. The higher the number I set the controller at, the more pronounced the lunging.


I think I read somewhere that it is in the car's programming/tune; it's just not noticeable until the controller amplifies the signal.

I don't get it. WOT is WOT. It doesn't make the car any faster, does it?

Look at the graph I provide in post #13. All manufacturers provide a slow tip-in to make it less sensitive in "normal (old man)" driving. The C7 has 4 levels of throttle response. The fastest is when in Track Mode in my 2017.

I was using the GM Max response in my none MRC 2014 C7 for 3 1/2 years so got used to what appears to be a linear not slow tip-in response. I keep my Vitesse set at 4 and IMO it matches what I had in my 2014 set at the OEM Max.
