All of the "normal" base strategies we use for the Phoenix chip have the high idle feature left intact in the tuning.

When using a programmer, it depends completely upon whether or not the pcm in the truck is programmed for it.

For instance, on an E99 auto truck with FUT4 will NOT idle up automatically regardless of temperature. A XLE4 (which is identically programmed other than the auto idle up) will do it. Same model year, same exact programming....except that feature. Using a programmer such as an Evolution/Gryphon or Superchips etc. will cause a non-auto high idle in a FUT4 truck. Using a Phoenix chip in a FUT4 PCM will give you that feature because the programming on the chip will be XLE4 programming.
