Anyway to "correct/better" the DIC MPG Average after supercharging a truck?

My truck MPG is between 5-7MPG different from what the dash display shows; is there any way to enable the now almost useless display to be closer to actuality? I understand it's merely an approximate efficiency display, but it's mildly annoying having it be so far off...the only benefit I suppose is my wife thinks the truck is almost a Prius but in reality it a super swamper bogger locked in 4WD...any suggestions or suck it up and be happy (rhetorical question)...

 

If you have a Bullydog tune they corrected that in their updates to the ECU program. Mine use to read 19 mpg now its reads accurately with 7-12 mpg where it should be.

 

Thanks for the suggestion...I had the BD tune and program however, I'd like to assume I've upgraded the tuning with OVT and I'm not sure if that can be addressed....yet...

 

I think the most effective solution is to remove said supercharger and donate it to me for science.

 

Haha I'm not sure I could ever drive a gasser if it wasn't for this SC...but I'll keep that in mind

 

I'd even let you pay shipping. Aren't I so generous?
