If I get a predator can I expect any kind of mileage gains or lessening of gas mileage by using the standard performance tune? I get about 15.5 MPG right now half city half freeway doing about 70, is that low already for a 4.8? I am trying to figure out if it is worth 350 dollars a year in higher octane gas since it is about 1.99 still in CA...so, little help?

 

I don't know if my mileage has improved or not. I get about 18 when I baby the truck, otherwise I get about 15 for normal driving, which is flooring it everywhere I go!

 

My mileage went from 14.6-15 to 15.5-16 with the predator. Even with the cam I have now, I am still getting 15.2-15.5
