GEN 1 Daily Driving with Supercharger

Mine has the Jdm tune as well, but I have only had it during the cold weather. Mpg may go up a bit with warmer weather and no more morning remote starts burning gas while going nowhere.

2012, whipple, daily driver since new, blower went on ~4 months after purchase. When driven apples to apples, on road, in a legal fashion I don’t think the fuel consumption is significantly different pre/post forced induction. If you drive it like you stole it, yes it burns significantly more than naturally aspirated. I get 12-13 around town and kiss 15 on long trips at 55-65 mph. Similar issues w belt shredding and what I’d call violent 1-2, 2-3 shifts when on dry roads and hooked up. I think it is a Force tune, running ~12 psi boost and no less than 91 octane. Im geographically challenged so control the belt shredding with my gas pedal but might some day investigate a different tune. I wouldn’t call the truck in original form underpowered but it certainly is a whole different animal now. I can’t imagine ever going back. Best money I’ve spent other than lasic and divorce.

I average 12.5 to 13 overall gas mileage in my 2014 Roush with JDM tune. Best upgrade was the JDM tune. Much better shifts and overall drivability. I drive 50 miles round trip Monday through Friday. Usually costs about $140-$150 a week for gas now.

Whipple Charged and daily driven in NYC traffic 10 mpg.
Highway 11.7-12.3 @65+ mph.

2014 Roush get 15+ but keep the stomps to a minimum and CC at 65

I get 10 to 11 whippled with 3.25 pulley

you are looking at it all wrong. . . its all about smiles per gallon

2013 Roush Stage II, 44K miles, averaging12.2 mpg combined city/highway. Premium fuel, of course.
If you stay out of the boost, the supercharger doesn't really draw any power and economy is on par with a naturally aspirated Raptor. If you have a heavy foot, your mileage may vary.

 

[roush_14]

You are totally correct. The supercharger adds a lot to the smiles per gallon.

Like everyone has stated, if you are beating the pissoutofit you wont win any MPG records, but the tune makes a big difference. I had a 14 factory Roush that got better mileage as soon as I ditched the Roush tune and went JDM. in 120,000 miles the lifetime milage was 11.7 which is better than my naturally aspirated 2011.
