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�ve had it installed for about a month now and my transmission started slipping and missing shifts, not sure if it�s because of the hydra or something else. I haven�t had any transmission issues prior to installation and it is a new beefed up trans. It was great until it wasn�t lol

I�ve ran this chip in my 7.3 for about 4 months now and I have to say I love the responsiveness and power. Only thing with this chip is I have not had good shifting with it at all. Easing around it�s great but when you get on it it shifts really rough and often slips. Contacted PHP which was no help which was aggravating. Other than that really solid chip.

Product seems great, it certainly wants to wake my truck up as I heard from many other reviews. However I cannot seem to utilize it because my egt gets to 1250* if I'm more than 1/3 to 1/2 throttle at best for anything more than a couple seconds. I live at high elevation and am using the truck to tow less than 6k (99 350) the grades are steep and I'd like to be able to do speed limit up them. I think once I do some more to the truck and get the egt down this will be the game changer everyone says it is, and I do really like the versatility. But for now its just making me feel like I need more stuff just to use it. Maybe I need some other non canned tunes too, someone told me the php tunes run hot up here and their custom tune dropped their egt 200*. For reference I was pulling a hill on the interstate at 45 in second (auto trans) well over 2200 rpm to maintain 1050-1150* I feel like I live in about the harshest towing area you can though so I can't expect the same results as other mostly stock users at lower flatter areas with straiter roads. Mostly just used 40up tow, and bumped to 25. Yes yes up to the 65 or 80 empty but same issue with high get and lots of black smoke when getting deeper in the pedal. Don't think we ever managed wot.

Took off my edge evolution and threw this on. My truck ran the same as with the edge and I actually had bad shifting with it. Shifting too early and very soft shifts. Communicated with php and verified my hex codes and all that and no helping the situation so I took it off.
