Today i was playing with my vag com and used the acceleration program in it. I didnt know you can get 0-60 from that so i was excited! I didnt get to use it on my A6 4.2 but i used it on my 02' MB Ml500 here are the results i got:

Power Braking 2500 RPM: 0-60 7.1 Seconds
Power Braking 3500 RPM: 0-60 7.0 Seconds
No Power Braking: 0-60 6.7 Seconds

All i have done to it is a K&N Air Filter and MB has the 02' ML500 listed as 7.7 Seconds i shaved a second off that time.

Within the next couple days i will test my 4.2 A6. Im Hoping to get into the mid to high 5's. I have RS6 Exhaust, Re programmed ECM and TCM and Cold Air Intake. I should have around 340HP. The stock C5 S6 with 340HP did it in 5.6 so hopefully i get good results.
