I'm reposting this. I'm new and I posted it in the wrong place the first time. Sorry.
I have a new 2012 Latitude. My only complaint is the gas mileage from the 3.7. I put in a K&N filter and install a Diablo fuel management chip. It's actually a modular the splices into the mas air flow sensor. What a difference. I really didn't think it would work. But between the two I've increased the HP and I'm getting almost 5 more miles per gallon. That's HUGE !

Like I said I didn't belive it myself. The surprising thing is that the chip was only $22.00 with a 100% guarantee. ! I figured what do have to lose. I was told this buy someone who installed it on a Silerado. I to didn't belive it. As far as the manufacturer doing it on the line. There in bed with the oil companines. Why do you think gas mileage gets better evey year. The forced to do it. Go to DSC Performance on e bay motors to check it out. I don't care who belives it. I'm laughing all the way to the bank !

The K&N was in first. I only saw an average of 1 to 2 miles per gallon difference. The combo of the two gave me the 5 miles per gallon improvement.

That's cool man. I'm glad about Ur increase in mpg. A super coil and performance plugs and wires. A good throttle body cleaner will help even more.
