I've been getting the low fuel rail pressure error and go into limp mode occasionally when towing. In trying to monitor the fuel rail pressure with my Predator the desired pressure goes negative when I get after it. It doesn't go negative when being easy on the pedal. This happens with and without a tune loaded. Does anyone know what's going on and why it shows negative pressure?

As for the P00087 error I've changed the filter and also the pressure relief valve. I thought the valve fixed it but it happened again last week. I'm having the injectors checked out next week.

Do you have a lift pump installed?

I do not have a lift pump. It's moving up the list though.

I haven't gotten the limp with the stock tune installed. At least so far. It's only happened with power tunes.

I would recommend a Kennedy Twin lift pump setup
