Can anyone tell me if I need to change the thermostat to a 160 degree thermo on my 04 F150 5.4 to run with the Hypertech Performance III chip? Someone I know told me I should but can't seem to be able to find a 160 dergree for an 04.

Welcome to FTE darrin66. Im not sure. Your best bet is to give Hypertech a ring tomorrow and see. I cant imagine that you would have to.

superchips programing

What type of performance upgrades can one expect from doing this?

Specifically, does it improve MPG, HP, and torque? I am considering this but would like to know what y'all have seen when doing this.

I have a 2003 F150 with the 5.4.

Thanks in advance for any replys

Hypertech chip

The dyno charts show a 25 hp increase from stock at 3,500 rpms on an 04 5.4. Check out Hypertech's website. They should have the dyno charts for your 03 also.
