I am looking for an affordable way to increase MPG with my 05 Burb.
I've googled many different chips and additives. There is an overwhelming amount of options.
Has anyone used any of the plug in chips and seen significant results?
I have read a lot of additives that claim to increase MPG and I am not sure of which of them to believe since they are all promoting their own product.
Also I was told that by burning E85 you can add a supercharger to the vehicle to increase MPG.
Any and all suggestions will be much appreciated.
Thank you all!

 

Welcome to the forum.

Assuming that you have a recent tune-up and everything else is in tip top shape, I don't know of anything that will increase your mpg. The way you drive has the most to do with your mpg. The aftermarket stuff is just a way to separate you from your money. Never heard about a blower and E85 since E85 has about 25%-30% less energy.

Black Bear Performance can do an "economy" tune. Check 'em out on the net.
