I have a 88 f150 xlt lariat 4x4 5.0 EFI 4:10 LS - 93k.. all stock
anyone know if I can put in a superchip to enhance the performance without
radically changing anything electrically? If I can ..what do I mess with first?

 

You can bump the base timing up 2 degrees (or more as long as it doesn't knock/ping), and that will be noticeable, and it's free.
