Power Hungry Performance Hydra Chip for Ford Powerstroke 7.3L 1994-2003


The 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 green LED switchbox. Using the up and down buttons on the switchbox, you can change your tuning preset on the fly. Don't forget we also offer optional billet aluminum flush mounts for a clean OE install into your dash.

When you purchase the Hydra Chip, you will have the ability to load 15 specific tunes for your truck make/year. The Software program is a FREE Download. This Download will allow access to the complete inventory of PHP Standard 7.3L Tunes all at no additional charge. Tunes for modifications like injectors or dual pumps aren't included. The USB connection on the Hydra Chip itself will allow you to load tuning presets to your chip without having to take it to a dealer or send it back to us! Just plug it into your computer and download your selections, even while installed on the PCM.

This feature is especially helpful if you order a custom tune from a custom tuning company--they can email you the file (which is specific to your serial number) and you can install it yourself from the comfort of your home! Your Hydra comes with the USB extension cable adapter, you can even plug your laptop into the chip from your cab while it is still installed in your truck!

    Hydra PHP Tuner, late shipping

    Posted by Drayson Marshall on May 29th 2020

    So I can’t technically review this as I haven’t gotten it yet since usps really dropped the ball. However my expectations are high and everyone says the hydra is the best of the best for 7.3s. I can also say that the customer support at riffraff diesel is beyond excellent. Very quick replies and nice people. Only complaint is I wish they shipped with anyone but usps.

    Had been procrastinating on a tuner for my 01 f350 ccsb. I read reviews and saw almost nothing but good review but figured people were exaggerating. I finally broke down and bought a hydra, other choice was a ts or arachnid just because I'm cheap. I can certainly say the chip is worth it! In my opinion the truck reacts with the daily driver tunes the way it should have come from the factory. Builds boost easier and quicker as well as keeping the tranny where it should. Also, so slow engagement from gear to gear. Now crisp firm shifts from the 4r100. If you're on the fence, let my review pull you over to the side of Hydra!

    Also, a dremel comes in handy to modify the pcm mount. I didnt like the idea of bending the wires so I cut out a hole and fed the cables through.

    Also the ribbon cable was about 6" too short for the way I wanted to mount. Would suggest the 6' ribbon cable if not mounting it near the headlight switch.

    Easy install had it in the truck within a couple hours. Did the F650 dash mod also at the same time! Tuning it was easy also.

    They had my order shipped with in an hour of me placing it. Free shipping that delivered 2 days later. Was easy to install just following the instructions. Tons of tunes to choose from, way better than my old TS performance chip.
