Circle D vs Revmax Converter
-Brian
First, I have the 2E 4000 stall and it's too loose with the 3.23s for it to be a really good daily driver type of car. I think with 3.73s it'd get rid of some of the sloppiness I have. It drives fine, but it is a loud car, so the looseness is unavoidable. So I would recommend moving to 3.23s or 3.42s if you have 2.73s. It'll get the car moving in traffic faster with less RPM.
Second, because a loud exhaust is amplified on a stalled A4, I would get a quiet exhaust and a cutout (for when you need it).
Third, I would get enough stall to overcome the sluggish affect of shifting from 1>2 in these cars. I would say at least a 3200 with 3.42 gears (so you're n the right track - something like a 2B or 3B from CircleD would be great). That would make a strong car that can be daily driven.
But I would try to get as much stall as possible. With a quiet exhaust and enough rear end gear, it makes it better. And like I said, I do 4000 now and it's fine. But it's subjective. And the tune does help with it.
Ask Chris for something that will keep your traffic RPMs under 2500 with a 3.42 gear or so that has the best shift extension possible (or drop between shifts). As an example, the 2E I have has very good shift extension and does not drop much on a shift (800-1000 RPM). But it also needs RPM to drive in traffic. Part-throttle tip-in is pretty weak because of that. So like a cam, you have to balance out the low RPM drivability with the high RPM sparkle.
Much earlier I had a TCI SuperStreetFighter 3200 and that was so loose, the car barely moved under 3000 RPM.

And Tom, you have the 4B? Or 4C?
Keeping revs under 2500 and accelerating briskly is what you want for a street car. So the 4C is a good possibility as well vs the 3B.
I still need to get 3.73s in mine. I accelerate with traffic at 3000. Sort of. I'd love to get that down to 2500.
