I am wondering if your MPG go up or down once you do some basic mods?TBE MBC and tune.

 

Up, The car will breathe easier and be more efficient.

 

Great so i average 21 so maybe like 23-24 then?

 

i use to get 28MPG with my 05 evo 8 all it had was a TBE

 

Thanks for creating this thread and thanks for asking the same question I had in mind. My guess is that the car recieves better gas mileage since it doesn't have as much restrictions after the mods. The one thing for sure is that the gas goes so crazy fast when I'm driving hard. I know that's natural, but MAN...that's not fair!

 

Flows better, but the car is also very rich from the factory. You can get better gas mileage on strictly a tune, no part swapping.

 

it really depends on how you drive. In theory your mpg should go up with bolt ons and a nice tune, but if your getting on it all the time because you love your new power, then your mpg will fall

 

This is exactly what I was going to tell him. It's not "in theory though"....you will get better mpg with a tune for sure if your not beating on the car.
