4.6 performance enhancements

[etomina]

New at this game. Need help re adding 50HP or so to a 4.6--can invest $1000. Want to maintain speed limit in hills while pulling a trailer. Thanks in advance.

I think any of the mods that 2V GT Mustangs can do to their engine will work on yours.

better gears, exhaust, intake, and a custom chip would be pretty good for towing and around that total if you are 2wd


edit- 4wd will mean that the gears will blow your budget. however, they are key.
