1. After retraining my brain for 1800 miles (about 2 months) I can finally shift smoothly 1-2, and 2-3rd. Have not mod. the CDV but I did add a 10M bolt to stop the clutch pedal from going to the floor (that helped a lot but still it took some more getting used to the timing of gas vs clutch release). BTW, I've been driving stick for 25 yrs....
2. The ride has smoothed out a bit. Perhaps the shocks/springs/tire walls have settled and softened up just a tad, which is a welcomed change.
3. The cold engine rough idle problem is a bit more pronounce. Either wait 1 minute warming up the engine or keep revs around 2k while driving out the first 1/2 mile.
4. The brakes feel more catchy
