The Power Hungry Performance Hydra Chip includes 17 total memory slots for tuning presets (15 tuning presets, NO START, and MODULE BYPASS) to get the most performance and efficiency out of your truck no matter where or how you are driving! On the old, 6-position knob-style chip, you could never tell what preset you were running unless you counted the knob's clicks. On the new Hydra Chip, you can always see what tuning program you are running with its convenient LED switchbox. Using the up and down buttons on the switchbox, you can change your tuning preset on the fly.
