I'm running there new tunes in my 2010. Very impressive, the XRace tune has a bit too much smoke for daily driving at my elevation, but it rips. I've really started to like the 215hp tune for overall driving.
Right now I use the tow tune and the xtreme street. I love them ! I will get the upgrade tomorrow. With the race tune, should I delete the egr cooler? I use it for a everyday driver and April- November I tow a 11,000 fifth wheel about every other week. Should I delete the egr cooler if I use the race tune?
My mpg has dropped a little also with the mild, but not that bad. It might be because I am at a higher RPM all the time cruising. I dont know much about diesel tuning, but I would bet that the injection timing is down at lower rpms.
next time I drive out of town unloaded I will load the street or x-street and see if the MPG is that much different for me.
I took the hour drive to see Eric and get the new tune. Extreme mild is a great tune and so far on the ride home I like it. I like to thank the guys at IDP, the knowledge they have is top of the line. This is my first diesel and I now feel like I know the 6.4 like I know the 5.0, 351w and 427. There shop was real nice.
