Predator part number: U7170
Predator Revision: v.9r05
2000 Ford Excursion Limited 7.3 Diesel

I just bought the Predator and I'm wondering which tune is the one to be used for fuel economy? My options are 45hp, 85hp, and 110hp. I'm currently using 85hp. I have noticed that since using the Predator at 85hp, the truck vibrates when shifting from 4th to 5th gear. Is that just a quirk or can it be taken care of with proper programming? Lastly, when shifting from 1st to 2nd gear it feels like the truck jumps forward a little bit. These are things I'm noticing since using the Predator and I'm wondering if I installed it incorrectly or if I need additional adjustments or programming to the Predator (gear type, tire size, etc)? Thanks.

You'll get the best economy with the tune that you are using. Drive the vehicle for a little while longer and see if it smooths out some, the control modules may need to do a little bit of learning.
