Re: Predator u7137 help

^ yeah we have some hills, but most of them are on the west end of the state. and don't get me started about the wind, my truck (work) has been leaning over like it's trying to make a " v-8" commercial for way too long!

Re: Predator u7137 help

Thanks for all the help guys.

I have averaged between 17 and 17.5 mpg all week, much better than before the Predator. I have stayed with the 87 perf tune. Might try the 93 shortly but still thinking about it. If I can justify spending 30 cents more per gallon for a few more mpg's, it will be a go. Working on running the 89 out of the tank right now.

Highway, right? You're not averaging that with city driving in the mix are you?

Re: Predator u7137 help

OK guys changed the EGR out this weekend. Mileage is up to 18.5 over the last 2 days. This is going in the right direction. Going to load the 93 tune for the rest of the week and see where it ends up. By the way the EGR solved my slight back and forth surging at highway speeds. Also quieted down the Hemi tick at start up modestly. I have the MDS off and it seems to run better and still seeing the 18.5 at 70 mph back and forth 50 miles a day to work.

Re: Predator u7137 help

My jeep seemed to run much better on the 91 performance tune. Loaded the 93 and it didn't feel as quick off the line and snappy in the mid ranges. I've just been running it in the mpg tune for a few weeks to maximize economy, and it definitely doesn't run as well as the 91 or 93... But 20-22mpg flat highway at 65 mph is worth it.
