Im moving to Mexico and im concerned about this humidity factor for the ecoboost shudder and limp mode problems. any good advice? should I think about cold air intake free flow exhaust? Or just leave as stock? thoughts or experience in this sort of thing?

 

Just get the update done before you leave......

 

What part of Mexico? A lot of Mexico is hot and dry I doubt you'll have problems there. Get the updates and if it becomes and issue drill the intercooler. Ford can't do this because of emissions rules but it has solved the problem for a lot of people.

 

I think you should worry about fuel more then anything. PEMEX fuels aren't near close in quality as you average shell/BP/chevron here in the states. Fuel filter and fuel system cleaner oughta be on the list for regular maintenance

 

Have fun with the fuel filter change! The filter is built into the in tank pump assembly. However, the Lobo might have an additional filter that is added. It might be worth checking into seeing if this is true and retrofitting one to your F150.
