I just recently purchased a predator (U7151) for my 2006 Ford F-150 and the mpg has gone from about 17mpg to about 13-14mpg on the 87 octane setting. The question I have is, is there a way that I can inprove the MPG using the Predator? I reset my truck to the original setting, but I have not seen any difference. And NO I have not been driving like a "bat out of hell."


any thoughts?

i had the same issue not much improvment on MPG but a noticable diff. in the performance. and my MPG stayed the same at 19mpg weahter i'm ,in or out, of the throttle pretty syeady.

If you guy's are going by the display for MPG it is no longer accurate with a tune installed on the vehicle. You will have to calculate it manually to get your correct MPG numbers.

Due to the performance increase with a new tune, most people are tempted to "get on it" more often. This in itself leads to poor fuel economy...I have learned this through my own experience!!! LOL

i understand all this but when you drive 40 miles round trip on the highway everyday to work you can watch your miles pretty good. and i get right at 18.5-19 mpg consistantly tank after tank. weather i put my foot in the fan or just cruise with the flow. so who know at least its not just god awful MPG,ya know??

I had the same results concerning the mileage drop when I loaded the 87 tune (9r04 rev.) but when I downloaded the 9r08 rev. and installed it my mileage and performance increased over the stock tune. For my truck the 9r08 rev. was a noticeable improvement over the 9r04 rev. I noticed the same drop that you did on the highway of about 3-4 MPG with the 9r04 rev.

Good luck.

So is there an economy tune? Somethng we can do for the other 75% of the time

So let me get this straight, this gadget is touted as a performance AND MPG enhancer but the MPG part isn't true?? I'm feeling ripped off here; I notice the quicker throttle response on my F150 and gotta admit it's impressive but I bought this thing to boost my MPGs...

No I saw the post, but I'm using the 9r08 rev and still see no noticeable improvement in MPG. I have run the same 200 mile route every weekend for months at 72mph (cruise control) and my mpg is 16-18. Predator has no effect. Is there a parameter or 2 that I can wiggle to try and improve it? What does the different MAF Curves do?

i noticed the drop when i downloaded the 87 but i downloaded the 93 on my truck and it gets 18 to 20 mpg on the highway

Ok believe me or not new 4.10 gears and a bama chips tune and I am getting 23-24 mpg on the highway and steady 19-21 intown so you may be getting poor mpg from load detonation by trying to be to conservitive
