Acceleration runs in 997S vs. 335xi with GTechPro
Hi, just got a Gtech Pro RR accelerometer and did a few runs in my 997S and my new 2007 335xi which has received a small tune using a piggyback setup which adds a few HP (juice box stage 2, check bmwjuice.com) and not surprisingly p-car kicked derriere but the all-weather turbo 4 door got 13.1 1/4 mile and 4.65s 0-60 which is really great. Watch those little 335's is all i can say, some have up to 400 whp with a simple piggy back computer for $1400... compare that to the $17k for the 997 performance pack... 
997S Best run:
60ft = 1.853s
330ft = 5.320s
1/8 miles=8.199@88.15
1000ft = 10.641s
1/4 mile= 12.699@110.02
0-60=4.285 s
335xi best run
60ft = 1.999s
330ft = 5.557s
1/8 mil = 8.524s @ 85.36 mph
1000ft = 11.030s
1/4 mile = 13.158s @ 105.96 mph
0-60 = 4.645 s

However, my car is chipped, K/N airfilter and supersprint exhaust. I hardly noticed the difference in HP.
I never get excited seeing a BMW, but a porsche, no matter the make or model, always gets my blood flowing.
