|steve05ram360||Yes... yes you do. I need to update the HP Tuners thread with some latest findings... I am pretty sure mpg has jumped again & may be closer to mid 22's this tank... in cold weather.|

|59turbo||Man, I really have to try and get a handle on tuning my truck with HP tuner. The gains you guys get is amazing.|

Go back to the stock airbox with an afe torque tube or cool hose with an afe pg7 drop in filter. I woukd bet hour mpg would jump ~1 mpg. Then do the 200* tstat.
Did you do any of the suggestions i made earlier in the thread?
And hand calculate a few tanks to validate the bully readings...

Since i i posted this i have been averaging 13.87 mpg. Bullydog shows roughly 13.5mpg so i back off my -14% to -12%. Plan to run that for awhile.
Yesterday coming home tanked my mpg due to a 45 mph head wind. I think my live reading was 8-10 straight into the wind. Probably not too terrible running 70-75 daily. Every day heading home it always seems like i am into a head wind. Another path just on highway doing 60 it seems to show 16/17 mpg but i haven't taken that path for a full tank because i would like to get take a straight shot to work.

My brother used to have a 70 Cuda... that was a fun car.
Always glad to share the info and glad it helps some. The biggest thing I've learned is there is really only one right answer when it comes to tuning, having the pressure spike occur at the right time for the given amount of fuel & air. The hard part is getting it consistent under all conditions. The push I got from Cpitock to retune in the cold was an awesome push...! Absolutely love the way the truck runs now.

Thanks for documenting all your methodical MPG experiments BTW.
I know engineers who calibrate diesels to get through emissions and driveability for OEMs who are less methodical and less detail orientated than you!
As I look at my map and tune via HP Tuners, I'm looking at timing tables I have of Hyundai industrial diesel engines, a 6.7 cummins and a commercial 2003 5.9 cummins for comparison but the stuff I have isn't as extensive as your stuff!

Steve, yes it would but I can only do so much right now. That would involve taking the radiator and intercooler out. I will do it, and I may either use a hammilton or design my own cam, but it makes sense to do it when I get my head gasket and bolts done.
I need to focus on my other projects, I have 14 cars!

Yes but you'd be doing it blind... you could take over the baro sensor on the airbox and adjust its output. You'd need to be monitoring the sensor & performance to know how much to adjust.
I have played with the baro correction recently and noted that when the pressure is @ 14.8psi, truck runs better than when @ 14.6 psi. Took a stab at the correction table with a very minor tweek and I could see a change, pretty sure I did not log it to verify, just left it as it was and rolled on.

|hiperf2007||I haven't really looked hard into over just running this bullydog 40420? But is there a way to manually play with timing? Something to plug in a trick?|
