I just bought a 2000 Ram 1500 Quad cab 4x4 with a 5.9l motor and auto tranny. It has an Airaide intake system, dual exhaust, a Trans-dapt throttle body spacer, Venom 400 performance module (turned off). Here is my question what approximately should my fuel mileage be? The onboard computer system thats in the roof with the compass says I'm getting 11.9mpg but I'm not sure how accurate it is. This is my first tank of gas so I haven't had a chance to check it manually yet. I am not a lead foot in this truck.

I have another question will the throttle body spacer hurt my fuel economy? All of the stuff listed above came on the truck when I bought it.

 

The spacer is a waste and might actually hurt milage and power. I'd take it out. Other than that 11.9 isn't bad at all for a 360.

 

again 11- 13 is avg to many human error factors for prius like dreams......

 

I am considering taking the spacer off. On the Venom website it says if it's off then it doesn't do anything so I guess I will just keep that installed for when I'm feeling sporty

 

ppl have done the ,intake ,sct tune, gears, exhaust, headers, cam, heads, everything upgradeable imagined and still get "around " the same milage so im not even gonna bother myself thanks ppl for being the guinea pig on this one. just gonna drive it and fix what breaks down the road. these trucks are not pratical Hp makers or milage increasers. IMO

 

Doesn't do anything when its on either.....

 

Im getting around 11 mpg in my SS/T. these trucks dont get good gas milage at all. but can make some descent power (just depends on how deep your wallet is)

 

Here's my gas mileage:

 

Here's mine:

 

I love it! Too Funny!
