I have a 2001 F-150 XLT 4X4 XTR. It has a 4.6 LTR V8. i Bought 22ft travel trailer tows fine on flat roads.But on hills starts to slow way down. The truck is rated to tow this trailer.....I installed airaid intake system and vortec exhaust from cat back......is there anything i could do to get real towing power out of this 4.6ltr v 8 automatic transmision......please help

 

The Diablosport Predator helped my 5.4L. It tows much better now.

 

I have purchased but not yet received a Diablo Predator.

I have read a lot on the forums and have ssen where some say they are using the performance program to tow and some are using a tow program.

Why typically is different between a "tow" program versus a "performance" program.

I plan on using the default Diablo Performance program for towing. Should I consisder modifying it for towing??

Thanks in advance

The difference is how agressive the timing is and shift patterns. Try it out and play around with the settings.... find out what works best for your needs.
