Vitesse Throttle Controller - Wow!
That concern was completely unfounded. SP0 is my custom tune and I found that SP6 is the setting that I like the best. I can alternate between SP0 and SP6 and really tell the difference in throttle response. This controller really compliments my custom tune. I'm happy that I have both.
Anyway, most are installing it in the ashtray but I really didn't want to drill a hole in to her. So, I thought I'd post some pics of where I mounted it. 
In this photo, you can see where I mounted the other module piece.
I've got the controller up and out of the way. Once you decide on a number you prefer, it's not inconvenient.
After getting it all buttoned back up. Nice and clean!
Auto--I think if you hold the button down (don't press and release, press and hold..) it will turn everything on but not start the engine. I know there's a way to do it. Maybe you don't press the brake or something
My C6 is an A6... with my other cars being manuals and key start, I still get in sometimes and instinctively hunt for the missing 3rd pedal and ignition switch to stick the key into.
Since many of you have said SP6 works well, so that's where I set it. Now the throttle is much more like my wife's Audi...instant throttle response. It will take a little getting used to, and I may end up backing it down a bit, since I'm pushing nearly 600rwhp. The great thing is the tune-ability of the unit. SP3 or 4 may work best for my application. Regardless, having 9 settings should allow the user to find something that works well for his/her own application, taking into account one's own sensory input. My "feel" from my right foot is different to a degree from the next driver.
Seems SP6 when I'm at ~1/2+ throttle, the throttle blade is wide open. It's pretty aggressive.

YES, when the CoW BOOSTER! is installed we are actually Changing the throttle mapping in the ECM.
2005 Cars have 3 throttle maps selected with the TC button and 2006 - 2013 have only 2 modes.
Since most customers have our AutoCal device, we can send you an infinite number of throttle maps to chose from.
NOT ONLY can we ENHANCE the throttle to ANY LIMIT WE CHOSE (no other product can do this),
Our AutoCal device can use the same custom throttle programming of CoW BOOSTER! to create a very unique
VALET MODE. Using our AutoCal device, the throttle can be programmed to TOTALLY LIMIT the
throttle so that a VALET at your local Golf Course, Country Club, or parking garage can only have just enough throttle
to park the car and NOTHING MORE. Flooring the throttle will only let the car idle along so that it can be safely parked.
There's a separate module called the "TAC" or throttle actuator controller. HP Tuners cannot access this module.
The problem is that even if you change the throttle maps on the ECM, the TAC module is still programmed to the original maps of pedal position vs. throttle blade position.
So, if you change the tables in HP Tuners too far.. The TAC freaks out because it see the throttle blade is in the wrong position compared to the pedal based on it's [still] stock settings.. and voila, Reduced Power Mode.
This device gets around that by manipulating the signal coming out of the throttle pedal.
Your ECU will not allow you to increase the Throttle response as much as what you have now with the Controller.
We did some testing with HPTuners on a 5th Gen Camaro V8 and the maximum increase we were able to get was not more than 30% of what the Controller could do. In other words, you get 3 times better response with our Controller.

We actually program the throttle controller at it's core. Our system works EXACTLY as if the GM engineers wanted it our way.
CoW BOOSTER! has now been around for 4 years with ZERO failures or problems and is the SAFEST! and most reliable
method for enhancing your vehicle's throttle response to ANY LIMIT WE CHOSE.
Our CoW BOOSTER! is available for Every C5-C6-C7 Corvette as well as every single GM VEHICLE SUCH AS....
CAMARO, GTO, G8, COBALT, CRUISE, TBSS, SILVERADO, CTS-V, ESCALADE, TAHOE, DENALI, DURAMAX, and just about every
application of GM vehicle you could want.
Instant Power, Instant Throttle RESPONSE, and usually up to 3 MPG in better gas mileage.
And best of all.... You can now get it TOTALLY FREE!

Stay (CoW) TUNED!

The vitesse throttle controller took care of all the trans shifting issues as well as any lag and gives you full control. takes 5 minutes to install.
I just got mine and it's better than they say...
No codes and car is so much better, I'm guessing this is what the COW BOOSTER felt like when that was the only option





I compare it to the change from analog tuning to electronic. With carbs and points, you needed screwdrivers, a handful of jets, timing lights, wrenches, and lots of time. With the advent of fuel injection and electronics, you only need a simple box to plug in the OBDII port and a couple of minutes to push some buttons.
With throttle controllers, the new kid on the block has the independent box with owner controlled buttons, that the owner can install in minutes, and remove and resell if desired. The fact that it has 16 choices of advance or retard instantly available, even while driving, is huge. Simply push a button to match your mood or for hwy, city, wife, son, drag strip, road track, mechanic, or valet, without waiting for the only person in the world, who tries to guess what you need, and then only when they become available.
In with the new and out with the old, it's called progress. You can't sell rooftop antennas as part of the deal, just because you include a free tube type TV.

First of all, Chuck and I have had conversations about his marketing. I'm not a fan. BTW if you ever meet him in person you won't believe the guy in front of you writes all of that.
Despite that, his product works.
In this case, if I'm him, I think it's wise to adjust pricing when competition comes along. Understand that Chuck has nearly ultimate pricing power here - he doesn't need to provide a device, just a software fix that he can mail so mailing cost and his time (he's really good at doing this, takes only moments) are the only costs. He recovered his R&D time years ago so incremental costs are super low for each sale. His competition can't compete with that as they have to provide not only mailing cost but an actual device which costs something.
I think this is smart business by Chuck. Posting it in a "competitor's thread" may be a bit more direct than I would do but as I already stated Chuck and I don't see eye to eye on marketing.

Oh, and Chuck's solution doesn't add any electronics to the system - it merely adjusts GM's tried and true and extensively tested electronic system with redundant controls (such system was designed to be lawsuit proof after the Audi debacle). The competition ads a new electronic device to a very sensitive system. Electronics sometimes fail. I imagine its designed such that if it fails, it fails in a throttle closed state (as opposed to throttle WOT), I would design it that way if it was me. I had a similar add-on device to manually control my fan and it failed with the fan not running state (I noticed it when my car nearly overheated and I had to jerk that device off the car on the side of the road to get home, burning my hands and cussing like a sailor as you can imagine). If I was Chuck I'd trumpet that as a competitive advantage. But again, Chuck and I don't appear eye to eye on marketing!

On my older '96 Saturn, I had an after market Venom unit, taped into the wiring, which senses resistance on manifold vacuum, the deeper I stepped onto the gas, resulted resistance created more auto adjustment to air/fuel, resulted in a mild SOTP feel. Crude in today's standard, but similar concept to today's throttle controller.
For my 2011 Honda grocery getter, there is an after market, been out for quite a few years - 12 Step Throttle Controller and that is no joke. Similar to Vitesse's functionality.
This mousetrap from Vitesse certainly is gaining positive market response - quietly - all the while!

We have always enjoyed 1,000% reliability and safety without EVER a glitch.
We built it rock solid and decided to stay far away from riggs and patches to make it work.
Our product has been around for a long while now.... Time will tell....

My Prius comes with three settings from the factory for throttle response. I understand the C7 does too. It's becoming very common and it really does change the behavior of the car, regardless of who makes the device/programming.

What Chuck does is primarily controlled by Chuck. Yes you may have an option or two, but if you want anything changed, Chuck has to do it and it takes time and additional devices to accomplish. If you sell your car or trade for a newer year, Chuck's stuff goes with the car.
With the Vitesse, the car owner owns the device, does the install, makes the changes from 16 available choices by simply pushing a button, and can remove it to install in another car or sell it.
Price means almost nothing in relation to capability. Maybe a free 1990's brick phone is attractive to some people, but I don't know anyone who still uses one.

Only difference is as you properly point out, Chuck's gives 2 or 3 options for sensitivity for the user to select (unlimited before he tunes it but 2-3 user adjustable after he's done unless you have him retune it), whereas the new device offers 12 settings for the user to select (the designer chose from unlimited and gave you 12). This may be of some value, like my Hurst "dual gate" shifter in my '72 Hurst/Olds which gave the "man" gate on the right and the "woman" gate on the left (their marketing not mine, sue them for not being politically correct but remember it was the 70's). There was real value there as the "man" side had positive stops allowing ratcheting shifting at the track. As noted, my car has three settings. Frankly I suspect most folks will find a setting they like and leave it, like they do their HUD height and their seat adjustment, but I won't dispute for some, 12 settings vs 2 or 3 may be of value.

100%I too, previously - an "one time" - customer, bought a mail order tune. Around the same time frame, back in 2010 - some of us still remembered the Cameron Fiasco.
No confidence with the tune, based on Cameron's fiasco. Didn't want to end up as another victim.
Had no experience with EFILive back in '10. Being optimistically cautious and PM warnings/communications from a few concern CF members. Took me a while to study up and able to understood that joke of a tune. Suffice to say, my decision to cut the $199 as a lost was proven - a good one!
Confidence/trust is a thin line in my book! As is birds of the feather!
In addition, this thread is regarding merits of Vitesse, I for one have no interest to the "other" product.

Pretty much every application has been done....
Even the V6 cars and not so popular vehicles were done in the development.
Call any time!

BTW, I don't believe Chuck ever had the retard ability that lengthened the acceleration/deceleration ramp spacing or I'd bought one. He didn't seem to have a clue why that was worthwhile, because he isn't a racer. The retard feature of the Vitesse makes your "EXACTLY the same thing - nothing more, nothing less" statement invalid. When people who already have Chuck's booster and have purchased and used the Vitesse, say the difference is amazingly better with lots of choices, then that appears to be a technological advancement.
