on a stock converter car, gain is about .2; with a converter it is no more than .1.

Even a tight converter like a Vig 2800, Yank SS 3600, TCI 3200 will give you .5 and there's no hit to highway mileage, gear whine problems and normally no tuning changes to deal with.

no tuning required for changing gears? might wanna rephrase that..

I think it was no tuning for the smaller converter

Exactly the point. With a converter there is normally no tuning needed; a gear change requires adjusting the speedo and frequently the part throttle shift points need to be fixed too.

i always tought it would at least be 3 tenths quicker. of course if you can hook up. 2 tenths sounds like crap. not that 3 is crazy. why is everyone say that it feels so great then if it is a 2 tenth gain. i know a converter is better but i still have warranty and i feel a conveter would absoultly void it.

I think people say it "feels" better with 3.73's because the throttle feels more responsive and the throttle pedal feels firmer. Driveability is a different issue then improvement in WOT acceleration.

tell my computer and my 3000 tci there is no tuning needed.. and thats not what my dyno guy said either.. anyways there is nothing wrong with putting a 3.73 in especially if ever down the road ur going to run a cam ect, u will need it then, so do it now..

I did the switch when I had a ss4000 and noticed almost no improvement.

Seat of the pants feel when you switch gears is really amazing. The car feels soooo much faster but the track results show that gears aren't the place to get a big gain if you are starting with 3.23s.

I ran consistent 13.2@106 with 3.46. Now 13.2@107 with 3.73. So you gain MPH, but the ET gains are negligible. The biggest difference was the stoplight throttle response and city drivability. Much better, and city fuel economy is better. There is no diff. on the freeway.

Im waiting for my stally. I think a higher gear is better suited to a stall as it feels tighter.

My gas mileage did not improve with 3.73s, but I did see a 1 mph gain too.
I agree that 3.73s help tame a big converter.
There's always one or two exceptions, but most people run a converter without needing tuning. If you needed dyno tuning, it wasn't the converter's fault; the converter didn't change your A/F by much (if at all) nor did it change your timing. Before Edit & HPT, lots of people were running Vig 3600s and Yank 4000s without needing tuning. A gear change requires tuning if you want an accurate speedometer & odometer and frequently you need to redo the shift points.

Don't get me wrong, I think having tuning software is one of the best things an A4 owner can have. Being able to customize lock-up and part throttle shift points makes driving a modified A4 much more enjoyable.

I got 3 tenths but as u can see in my sig my traction aint worth a ****. That was on street tires. Defiantely could do better with better tires and if they were the right size.

I picked up three tenths going from 3.23 --> 4.11
