Replaced all 5 door locks on an Excursion and they all worked, then a week later the back doors and hatch stop working. Any ideas?

We generally see a 20rwhp increase with the regulated return mod. In most cases the engines run smoother and quieter. The HX mod is also another cheap fix that can quiet the engine as well as increase performance. Last but not least getting rid of the quick connects at the tank and pump inlet will also do wonders for the 7.3.

1) NGS with the Green Service card version 12.2. 2) Go to Service Bay Functions Press Trigger 3) Go to ABS Press Trigger 4) Go to Tire Size / Axle Ratio Configuration Press Trigger 5) Go to 99-02 F Series S-Duty Press Trigger 6) Go to Tone Ring Size (10.25) 120 teeth Press Trigger 7) Scroll down to (8.8) 108 teeth Press Trigger 8) Go to REV Per Mile and Press Trigger 9) Measure the Tire Circumferance in INCHES then Divide By 63360 That will give you the Rev Per Mile. 10) Multiply Rev Per Mile By 120, This is the Number of teeth per mile. 11) Divide the Number of Teeth Per Mile By 108 and use This number for your new Rev Per Mile. P.S. If you still need more range you can use a 7.5" ring gear it has 102 teeth. Hope this helps.
