13.0 Miles per gallon after Z-tube/pop Charger install

I've had a Z-Tube on for almost a year and have not seen any decrease in mileage. However, when I had the Z-Tube and the K/N CAI, torque went to **** and so did the mileage. Take off the PopCharger and you will probably see things improve. A drop-in K/N in the stock air box combined with the Z-tube seems to be what is working best for alot of people. If you go that route and still see lousy mileage, you may have screwed up the MAF sensor. Take it in and have them run a diagnosic only after you go back to stock. Dont tell them that you modified anything.

Thanks Guys,
I was wondering thou... since I got my car never did i Hit 19.MPG my max was 18MPG, maybe ther's really something wrong with my sensor, I'll prolly take it in...
By the way I drive at 405 every single day traffic is a b!tch or sepulveda pass..
If you guys don't know it's the worst freeway in US. It takes me 1hr 1/2 14 miles..

Kingter-there is NOOOOO way I am going to let my wife see this thread, whenever I do something to her car, I say ,"but hon we'll get better gas mileage", and she just rolls her eyes .
I think it is a combination of a tendency to drive more aggressively to listen and feel changes and as the others say there could be something not right. I would get it checked out(after you switch back, unless your dealer is cool with minor mods)

Before install I get 17.7 Miles per gallon now I get 13! is it because my ECU is reporgramming? is this normal?

I get 24 mpg on the interstate (~80mph w/ A/C on), and around 19 with a combo of city/interstate driving. I have a ZTube with the K&N Drop-In.

I've done this mod too guys and not noticed any decrease in mpg's.
If you do, then it's prolly from stepping on the gas more to hear the sweet music.
I'm not saying your mileage checks are wrong or inaccurate, but mileage should be checked over a longer period of time. This will take into account changes in weather, minor errors in calculating, and a host of other factors which affect mileage short term.
From it's design, I would say mileage should improve (tho fractionally) from it's install.
