Hey guys I'm new here. I need help "peping" my truck up. I have an 08 f-150 4.2 Rwd manual tranny. I love her to death I just need some more go go for low dough.

 

2 things that you can do.

1. SCT programmer with custom tunes. About $400.

2. Upgrade the diff gears to 4.10. About $800 including labor.

Exhausts and intakes will make it sound louder but do virtually nothing for performance.

 

What are some other options as far as bolt on or heads intakes....?
