Welcome to FTE,
No , you can not just have it reflashed to get that extra HP.

In 04 they came out with the 300 HP rating. It's a little different from your 99.
However you could mod your 99 and get close to 300. It all depends on how much money your willing to spend.
For about $3500 to $4000. you could do a Lightning conversion on it and make over 350 HP.
Or you could go with mods like electric fan /open exhaust/ K&N intake or other and tuner or programmer. All of this will get you close to 300 HP.

I thought the Pre-2004 5.4's made 260HP and the 4.6's made 230HP?
