WHATS A GOOD TUNER FOR A 5.4L. WHAT COULD I EXPECT FROM IT?

 

Well there are lots of choices when it comes to tuners. If I were you I would go check out the tuner/chip section of the forums. I have a 4.6 and I'm running a SCT X3.

Some of the more popular companies/tuners are

Edge Evolution

Superchips

SCT X Cal 2 or the newer model X3.

Generally speaking these tuners are supposed to add about 25 HP depending on what fuel grade you have it set on. It might also improve your shift points and give you slightly better gas mileage. Any ways good luck.
