Thinking of getting a TS performance 6-position chip for my 1997 7.3. I was wondering if the "High Idle" setting will also close the EBPV when idleing? I am also wondering if it is worth getting one of these chips tuned by Beans, Swamps, or Wildman over getting just a regular TS tuned chip. My only mods will be a DIY intake, guages, and a full turbo back exhaust. Thanks.
