My 7.3L PCM has a code of ZRE2. This translates to downloadable tunes for stock injectors. I was under the impression that custom tunes would be available for my PCM, but was told that my ZRE2 code was rare. PHP recommended a set of tunes that were close to what I should have. They work, but are not ideal. I will be following up to see what other options are available. So far, this has not been worth the $150.

Love it! The hydra titan unlock gives tons tunes for my strait shot injectors. The tuning smooths out the idle as well as giving great transmission shift strategy's. If you have larger strait shot injectors this is a must have. Even if you plan to buy some costume tunes this will fill the gaps and great for the $.

Got it super fast got them put in a must if running aftermarket injectors and now sky is the limit

I bought the titan unlock only to find out that there were only one set of tunes for my particular truck/injector combination, only to find out that it was not for a modified valve body auotmatic transmission, so if you pressed the throttle down more than half way in any of the tunes , the transmission would shift erratically up and down searching for the correct gear.......... essentially it was a waste of money and I had to get custom tuning anyways.

Completely amazed with how this chip transformed my work truck. It weighs 14k pounds and this chip on the 80 hp tow setting changed my transmission shift points for the better, got rid of the turbo surge and made this truck perform like there’s no weight on her at all. Best thing I’ve put on this ole 7.3

These guys are awesome. I ordered on a Sunday afternoon, and within about 3 hours it was unlocked and I could download tunes. Can't say enough about their customer service.
