Prior to having my Crossfire chipped I made some testing myself and here's what I gathered: Crossfire Auto 5 speed with K & N Filters :

OAT 57 degrees

( with ESP ) 0-60mph...7.94 sec.
( without ESP ) 0-60 mph...7.06 sec.

If Chrysler rated it at 7.1 without TC then the K&N filters delivered a gain of 0.94 sec.

I haven't tested it yet with the new chip
