With the truck LSX intake is there any real power difference between LS2 90mm throttle body and 102mm big mouth throttle body.

The LS2 are so much cheaper is what I am mainly getting at.

Did anybody notice MPG change from the stock truck set up?

 

I really dout you would see much of a gain, most iv seen use the 90mm, however unlike a carb your not useing the tb mix you and pull your fuel so anything before the runner is simply a restiction with fuel injection so you cant really go to big, bigger = more hp. But like I said it would be such a small gain I dout you would even notice it.

 

Ok cool that saves me some $$$
