I have a 2004 Sierra Crew Cab 4x4 with the 5.3l. It is not a flex fuel engine. In your advertisement videos they claim that you can use E85 in conjunction with your tune, is this true or are there other mods to be made.
I was also wondering what HP and torque increases you are expecting with the 87 ,89, or 93 octane tunes.

Thanks
Brian

Those are OEM Predators made for a company that specializes in E85 conversions. They are not released yet and will not be a U7193 part number.
The unit you have will not work with E85 fuels.
hp increase ranges from 10hp to 25hp in the different tunes.

Did you find the Predator worked for your truck . I have the same Truck I am thinking of Purchasing the Predator but not sure if there are problems with it. thanks Tom
