Would there be any advantage for a speed density tune for a NA 5.3L. I have been reading about the guys going sd for FI applications but not much about it for NA's. Would there be more power and possibly better gas mileage? Then how hard would it be to switch? I have tuning software and am pretty knowledgable about it just need a few pointers

 

its pretty simple to switch, but i doubt you'll get much if any better fuel mileage and the power difference would be minimal as well.

 

speed density, i have been told, is only beneficial if you are FI or maxxing out you MAF

 

that is what i figured just thought i would check to make sure
