Is there something wrong here?When my EMS was installed and simple base map was set up, I think I was getting about 13mpg on the way to the dyno.
My car was getting worse milage than my 2005 Expedition!

You need to see a tuner.

I see about those rates, but the car smells so much different now than it did before the ems, i have a test pipe and it has become much more apparent, i havent upped the boost yet. I will get it re-tuned when my 4.25" comes in. thanks

I also agree that its all based on your right foot 
but yea tuning also has a lot to do with how your car consumes gas.
The lowest I've ever gotten was 14.7 mpg, but it could've been much worse because there was some normal cruising driving involved in that tank. The highest I've ever gotten is 28.6 mpg with pretty much all highway cruising with very little load.
Now granted I don't have 750s, I have 675s but still your mpg shouldn't just suddenly drop like that. I would definitely get it checked out by a tuner to compensate for the upgraded injectors. And also as someone else said, if you have a wideband gauge, monitor your AFRs to see how rich you are running.
I'm very conservatively tuned, and under WOT in boost I see 11-11.5 (I don't have an exact figure cuz Id rather not pay too much attention to the gauge when I'm getting on it like that ). Under normal cruising with little to no load I see 13.2-13.3...

If you have a wideband check your A/F. I'm seeing low 14's when cruising at freeway speeds.
