It will go up from what you currently have.
OEM with Lidio tune = 22mpg
Add 410s = 20.5mpg (and well worth it!!)
Add Trilogy with canned Trilogy tune at 350 RWHP = 24mpg
Add Martyo dyno tune, 17* timing, 409 RWHP = 17mpg
Add my custom designed exhaust fabbed by Red at Martyo's with new dyno tune, 14* timing, 436 RWHP = 20mpg (16* timing shot it to 463 RWHP so Jeff had to dial it back as still OEM block internals)
So, ya, you can do better.
Good luck!

Not totally sure in your specific case, but with the 4.10's and the tune you should be even or just 1-2 loss from normal. Normal for me was 21mpg

Complaining about mpg with a Marauder is silly. We all know what we were getting into when we purchased this vehicle. We made our bed, we'll sleep in it.
However... complaining about mpg with a valid reason is completely different. As GDMJOE said.. It's an anomaly.
Even with a crappy supercharger or elite amp/sound system, No Marauder should be under 17 mpg. Are the fuel lines clear? Tank empty of debris? Saw another thread (not here on this forum and not a Marauder) that some guy got a leaf or something stuck in the tank and covered the flow from the fuel pump to the engine.
Now, how likely is that on your Marauder? I would venture slim to none. But can't rule out the outliers. One thing I've learned with ownership of this car is that SHE'LL fool you. I hope you figure out your gremlin
Also yes go to Marty for all things modification.

10 MPG average is horrible unless you drive WOT a majority of the time.
If not, the exhaust fumes would be awful at idle.

Hey y'all, sorry it's been so long. I totally forget about this thread, but it's been several months that I've had my Marty tune and I absolutely love it. I manage 15 mpg in my area in most of my tanks, although I still get as low as 10 sometimes, but I suspect that's just from the geography.
All is good, and thank y'all for your suggestion of getting a Marty tune. He does good work, and my car feels so much faster.
Thinking of maybe sticking some 4.10s in it if the fuel eco wouldn't suffer too much. Thoughts?

If you are really getting 15 mpg's or lower in regular driving you still have a problem. Your profile says your MM is NA. I'd take the car to Mo's and have them go over it to find out why your mpg's are so bad. You should be getting low to mid 20mpg's.
It's effectively stock. I assumed 15 was normal for NA but I guess not. My old '09 SAP CVPI with 3.27s managed a solid 20-25 in my town.
Luckily I live about an hour away from Mo's; I assume I just gotta give his shop the call and let him know what's up?
Now I'm getting a bit worried, considering how good of shape this particular car is in

My first Marauder was stock when I bought it. My first mod was 4.10's and a tune. Best bang for the buck!
You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference
I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard
