I just got my 2005 Hemi Ram running again. It needs a tune badly. Thus far, the PCM has not been able to figure out the new cam & headers. It hasn't been able to figure out idle either. It's an 05 hemi with a comp cams XFI 268 grind. It has 1-3/4 inch pacesetter longtubes. It will have a dual 3" exhaust with an x-pipe, but it's open headers now. It screams above 3K rpms, but definitely doesn't like being below 1500 rpms. I guess I need SCT ? Diablo ? I dunno. But, I need it fast. Call me (anytime) @ 732-690-5848, so we can get this beast humming. Thanks, Don
