Can the rear O2s be "turned off" if you remove the cats? HPTuners allows you to turn off hte rear O2s on GM cars if you remove them, but not sure about the Ford system.

 

Yes but you have to find someone that will do it. It's illegal. I had it in my last truck

 

If HPTuners will work with the 08 f150, I can do it myself. I have been tuning LSx cars for about 4 years and can tune everythign from stock to blown cars, but haven't checked compatability with the F150. If work will slow down a little, I will investigate and start doing some experimenting

 

What all is done to it and what motor

 

Just got it a few weeks ago and I won't do much of anything to the motor. (I have all the hotrods I need) I am changing all fluids and inspecting it. I was originally going to put a blower on it, but will just leave it for now. (4.6)
Looks like HP is compatiable with this truck, so I will begin researching trans settings, fuel and timing tables, and later this summer will start playing around. For now I just want a truck with a little more responsiveness and maybe a little more gas milage (for a 4700 lb truck)

 

Yea that's what my last truck was I removed rear cats and rear 02's and turned the monitors for them off
