Ok so I bought the hydra for my 1994.5 7.3 F-250 ZF-5 4x4, I installed it just like the instructions said. Truck won't start, check engine light comes on, wait to start light does not come on. So I talk with the guy that sold me the Hydra he loaded tunes for an automatic, no big deal. So I grabbed my BOX code BEG8, looked into the Hydra flash for my box code. Apparently my box code doesn't exist. What the hell??! So the tells me to try a few things, reconnecting, cleaning, and even loading different tunes. Still no go, same issue every time! Truck won't start, check engine light on, and no wait to start. Can anyone please help with this. Is the chip shot?? Thanks.
