G-Tech numbers, but haven't been to the drag strip yet for official numbers. I have the GanzFlow CAI, K&N panel filter, and a Stromung dual-tip axle-back exhaust. My 0-60 time is 7.1 sec, and 1/4 mile is 15.5 sec @ 90.7 mph. Remeber, G-Tech numbers, but there are my averages from many runs of both measurements. Hope this helps!
