The PHP Hydra is a J3-port tuning chip for the 1994.5–2003 Ford 7.3 Powerstroke. It mounts on the PCM and uses a two-digit switch in the cab, so you can change tunes without a laptop on the road.
It is not an OBD flash tuner. The chip plugs into the J3 connector on the PCM board. The switch has 17 positions: 00 is module bypass for diagnostics, nS is a no-start security mode, and the other 15 slots hold the tunes you load. Stock PHP files cover heavy tow, daily driving, economy, and performance, from about 25 hp on a heavy tow file up through the race files on stock injectors. Upgraded injectors need a custom file. Those are not in the standard library.
The kit includes the chip, digital switch, ribbon cable, and USB cable. HydraFlash, free for Windows and Mac, loads and verifies a position in under 20 seconds. It is PATS compatible. It does not fit a 7.3 IDI, including the early-1994 turbo IDI.

I have stage 2B injectors what would be the best tune package to go with?
A

Not familiar with 2B injectors. Any of our custom tuners will provide you with great tuning.

We only ship them blank. Easy to tune from home with the free software. We do ship Hydras with tunes when purchasing stage 1 or stage 1.5 injectors.

I installed the hydra chip a week ago and it definitely performs better. I would recommend getting if you haven’t already

Arrived very quickly, worked well, and came with a sticker

Installation was straight forward and the videos are super helpful…clean your PCM properly! Aaron was super helpful when I called and directed me to the cleaning video.
This product completely changed the whole attitude of my truck! Responsiveness and power are improved tremendously. Fuel mileage has already gone up even with heavy footed testing! So happy I made this purchase.

What an easy and amazing thing to do to an old 7.3. Mine had a SCT X4 installed previously and I bought this and wow what a difference.
