I never tested the SS just what I heard. My crossfire went 14.8@95 Now my 300hp N/A on stock tires and transmission, i got stage 2 n/a, chip, and racing exhaust, racing flywheel, 3plate clutch, carbon driveshaft, and stage 1 weight reduction. Ran a 12.9@110 :-D if the crossfire was like this lol that would be awsome. I dont think you can give the XF Fi in this. anywho on the bottle i got the XF at 11.7@128 still on stock tires.

Okay for the srt-4 I'll give some one mad props if they can get into the 14's. The best i have been able to do is 15.0@98.

One thing i have noticed is the gearing is off big time, my crossfire is hitting 60 in mid range 2nd Gear LOL. and the srt-4 has to shift into to 5th at 94. I can hit 94 in 3rd in my srt-4.
