upping the mpg?

a friend was saying by changing out my stock intake and exhaust i can up my fuel efficiency, any truth to this? and if so any suggestions?

In some vehicles this is true.. Not sure the LGT is a good example though. You would spend years trying to recoup the cost of the intake and exhaust in added mpg.

what's your current MPG?

I showed 2 mpg difrence from blitz to aem. Both were tuned to car when did the swaps.

You can't just drop in a new intake/exhaust in our cars. It would need to be tuned in order to run properly with those parts.

 

You could gain a couple mpg with just a Stage 1 tune. But don't expect more than 2 or 3 mpg.

Once you tune it you could see improvements. Then again the new noises from behind the glovebox can cause it to rapidly drop as well.

Even with no tune on exhaust mods, you could see an improvement.

 

There is a chance you will see an improvement w/ the intake also w/ no tune, but if you do, it will be because you are running lean. Which means your engine could go boom

 

Overall, anything that gives the engine more power (other than a turbo) is actually making it more efficient. So drven EXACTLY the same way, mpgs will go up.

 

The difference w/ the turbo is that the size effects how often the car is in boost. The more you are in boost, the more fuel you use

thanks for the help guys, gives me some stuff to think about... i'm avg 17 - 18mpg but all of my driving is city so I expected it to be a little low.
