I need some help - 4/30/2008 9:14:01 AM    Hisss04Cobra   Posts: 1769 Joined: 4/27/2005 Status: offline I have a 3.0 pulley plus tune. I'm ordering new exhaust and maybe an intake. Do I need a new tune for this when I put it on? _____________________________ Post #: 1

Get a custom dyno tune... do not cut corners with ur car... _____________________________ 2001 SVT Cobra 5.1L Stroker, Ported 04 Cobra Heads, Stage 3 Cams, 3.4L Whipple, 28 psi... http://cardomain.com/id/martinfrenchjr (in reply to Hisss04Cobra) Post #: 4
