will a fastman 50 or 52 mm tb improve my mpg? I have a 99 quad cab 8'bed 5.9 2wd. I do some towing but not much thanks guys.

 

alot of people have said it does improve gas miliage....but some people picker that the fact that your throwing more air will cause you to use more gas....but to be honest...it really depends on your right foot lol....give it a try and from what i hear you'll love the better throttle response
