I already had a Dyno tune on my 08, and later I put on a V-Max ported and polished Tb.The first hit of the start button I heard the different and on the street it made a Hugh different on better response. I'm not going to put anything on my vette that messes with the ecm.

What options are out there to make our dbw cars feel more like a dbc? Im not interested in one of those throttle "boosters" I'm looking for something that eliminates the lag from pedal blip to engine rev. Do I acquire this via a tune, or does someone make a PNP module? Most threads I searched are yielding older results with stuff im sure outdated now

BTW, I am wondering, and I have no info other than a notion, if the factory throttle response ramp changes when you switch off traction control. Anyone know? I think it could only do that with two throttle % maps and I am guessing the tune doesn't have that sophistication. I will know eventually.

So, this begs the Q. With a Vitessi and in traction control mode, do you still experience the more instant TR with Vitessi in a high setting?
Then, the Q, if in complete comp mode, no TC or AH, does the throttle % ramp change to closer to 1:1 without Vitessi?

And, its known that in traction control mode these systems utilize the drive by wire as a control device, if the BCM detects wheel spin the ECM can mitigate that by reducing throttle regardless of what your foot does. If extreme or if yaw is also present it will selectively add ABS.

FWIW: All these endless discussions about the throttle have turned me off to the whole idea of buying a Vitesse or otherwise messing with what works now.
Traction control, nannies, I don't know, are they the same thing or different? It's all very tiring trying to learn it all. My car (LS2, A6) will NOT spin the tires even with the nannies supposedly turned off (although I don't really care if it spins or not). I have no idea what's going on with the stories about out-of-control burnouts with stock C6s.
I either want my car as is, or give me an old car with a carb and steel linkage between it and my foot, where driver skill = nannies.

Yeah, that's probably a good test - All nannies off and try Vitesse in a couple different modes 0 - 5 - 7; and, if you could, one of the minus fuel saving settings. Are you capable of datalogging?

I'm not afraid of a 400 HP "nanny-less" car. I had a 390 HP Roadrunner when I was a 20 year-old fearless buck, no "nannies" of course, and it wasn't a big deal. I drove that sucker hard and never had any handling problems with it (other than hitting the drum brakes at 100+. That will keep you awake. 
).Having grown up by slamming lot cars around in the dirt when I could barely see over the dash taught me a few things I guess.
This stuff just doesn't mean that much to me anymore. I'm lovin' the car as is -- quiet, climate control, power when I want it, etc. Oh well, to each his own.

The term Nanny when referring to a car, is something that restricts you from doing something stupid or attempts to fix something when you already did.
Kinda like an automobile babysitter.
Things such as traction control and anti-lock brakes are a few examples.

Yeah...like TPMS....how ridiculous is that?? Then car guys spend the rest of their lives trying to defeat them. Started all the way back in the early 70s when they came up with all that Smog equipment...

AFAIK, turning off nannies will not make a quicker throttle response.

Yeah, you're probably right. As I'm getting more and more into the tune, that would require two completely separate throttle maps, and it wouldn't make sense for the MFGR to do that in production cars.
