I don't disagree with what you and vader86 are pointing out. I wasn't trying to suggest that they TB blades were being programmed to move differently only that the car's response was different and don't mean to lead the OP astray.
I drove the car that way for 60K and really enjoyed the perceived "instantaneous" response . Now it's been almost 2K on the new rearend and I will ask them about it.
Now that I think back on this, the years that this was my only car and I was driving it in the snow up and down hills in Seattle (a few times a year) was before the cam and original tuning work was done otherwise I may have been less successful driving in the snow LOL.

LOL these C-4s are old but not that old ,going to but that old 750 double pumper on that thing and its going to fast .. With the PCM or ECM or whatever one wants to call it . The electronics in the C-4 and all the rest regulate what going on inside the motor . The days of just slapping on something and saying I did good just can't jump the premiers of the electronics have to sit down have a long talk with the tune if add something have to tune for it ,its a new day scene 1984 . Yep a 750 double pumper back in the day would make anybody a hero ..

So yes, it would make you a one eyed hero among the blind. Today, that isn't as easy to be anymore. OTOH, it does give some good benefits. Not having to rejet or wait till the car warmed up to drive is a huge plus. Also if you really care about the environment and not just lip service, it is a huge plus. The downside is you have to put some work into it if you want to modify. All depends on how you look at it.
