I know free flow and all that BUT I am not that familiar with the particulars of these cars. I am just an old school guy who has built street cars but I do not even pretend to know the proper mods to warm up a Crossfire. I have had this car for 2 years and it has been difficult leaving it alone even this long ! ! I do know to ask people who have " been there & done that " before going off half-cocked. Any and all input is welcome ! Tim
