The PHP Hydra Chip is a multi-position tuning chip for OBS 7.3L Powerstroke trucks. It offers 17 calibration positions, including a Bypass Mode and a No Start mode, plus lifetime access to Power Hungry Performance's standard calibration library. HydraFlash software lets you program and reprogram the chip from a Windows or Mac computer, and the removable two-digit display switch lets you change calibrations on the fly. It suits 7.3L owners who want both off-the-shelf tunes and the option to load custom files from their own tuner.
