One other question for all while I'm at it: I have an 07 5.4 that is equipped to accept Flex Fuel. I've seen where there have been a few people with the Flex Fuel engines having issues with adding mods, programmers, etc.. Is there anything I should be especially careful about or look for that differs from the other 5.4s?

thanks for the help!

I'm not really aware of any specific problems in the 07-08 model year trucks that are caused by mods. As far as I know, the design changes were in things that could be "attacked" by ethanol, like seals and such. Possibly, there was a change in the design of the 02 sensors as well, but that shouldn't cause the problems you describe.

So, to answer your question, I can't think of any special precautions you need to take. There've been many posts on using E85 in this forum though, and most of them have been negative, due to the reduced gas mileage.
