Diablo Predator - Best fuel mileage, which setting?
My 03 F-250 is stock except for the Predator and I have mine on the 60 HP setting. I am getting about 19 MPG. Mostly highway. I have tried all the settings and the mileage doesn't change that much. Since mine is stock I don't feel I get the full advantage of the 85 HP setting so I didn't leave it on there very long. I also only have about 3700 miles on the truck so far. All in all the 40 HP is probably the best with stock intake and exhaust.

I am probably going to go with the lowest setting and track it first then work my way up from there. I just didnt want to go through 3 tanks of gas to wait to find out. Any others results would be greatly appreciated.

I notice power increases on every level. But with the 85 HP after about 3/4 throtle it only makes more smoke, not power. It is surely because of the stock intake and exhaust. After these upgrades I will play with the higher settings.

Ken, I have a stock exhaust on my truck w/ the Predator on the 40. I want to put the A pillar gauges on but don't think my downpipe is set-up for the thermo coupler. Do you know if stock downpipes have a plug in them, or should I just change downpipes??? Limited Budget!!!!!!
Thanks

Not to step on kens toes but i have your same truck and installed the tri pillar gauges on mine with stock exhaust. I got a clamp on type pyro and drilled a hole in the down pipe around 2 inches from the outlet of the turbo without removing the downpipe at all. It was a tight fit to get the drill in there but it can be done and still get a straight shot at it. The pyro install kits from autometer usually come with a weld on type fitting which is the best way to do it and clamp on setup all in one box. Hope this helps.

Anyone having mushyness with shift should call us about the middle of next week. Diablo has identified an issue with a small number of VDH related codes and an update to the Predator will be made available for those needing it.

I just bought the predator and have been using the 60 hp setting since I got it. I'm waiting until I can add gauges and a new downpipe before I try anything else. The increase in performance has been unreal.
Mileage-wise, I have been over 20 in almost all highway use since I installed the tune. I hit 23 last fill-up!
I have a manual trans so I haven't had any problems whatsoever.
Ken - is there anything more to the update? Should I send mine in for it pretty soon?
