I felt the same way you guys do although I've got an MS6. What made it a ton better was adjusting the APP (accelerator pedal position) tables in the Cobb ATR software and then uploading the map to the ECU via the AP.
The stock APP tables are not a direct 1:1 relationship between the rate of pedal application and the rate of throttle valve opening. Here are the first few examples of the tables where the 1st # is the pedal value and the 2nd the throttle value:
0:0, 2:.25, 4:.65, 6:1.68 ... it doesn't get even until 28:28.
I changed all of my APP tables (incl. neutral) to a direct 1:1 relationship so 2:2, 4:4, etc. just to get the direct feel I missed on my cable-driven throttle cars and not only did I love the snappier throttle that came with it but an unexpected side benefit was the car was much easier to get going in 1st with little to none of the jerkiness when stock.
You obviously need to already have a Cobb AP and the free ATR software to do this but if anyone does do it, don't forget to change the "0Neutral" table as well because if you don't you're still gonna get the jerkiness.
