U7158

2003 Ford F150 Lightning

Thanks!!!

I have an 03 Ford Lightning and u7158 tuner. Im running a #6lbs lower and custom tune. The back cats have been removed but, I left the pre-cats on. Should the rear o2 sensors and heater banks be set to on/off?

Thanks for the advise.

Thanks,

No bolts ons have been added since then. I have been running the same set up for over a year now w/no issues. The problems started after I ...

The truck no longer knocks or pings @ WOT. I am assuming the computer corrected the timing.

I tried downloading both updates because I thought they needed to be added.

The truck is sputtering. Sounds like the motor is misfiring or running on 7 cylinders @ WOT only. Other than that the truck runs ...

I have a u7158 programmer purchased from Steeda w/ the program to work with 12lbs of boost pulley. I just uploaded the newest version r10 and I have always had the programmer set to (93 octane w/pulley.) For some reason when I tried to download the r9 update I received a corrupt file message on the ...
