Upgrade MAF

Is it worth is to upgrade your MAF. My brother is wanting to do it on his 5.4L http://www.granatellimotorsports.com/fordmaftruck.htm.

They say it adds 10-35 HP depending on your application http://www.granatellimotorsports.com...no002small.jpg

Is it worth is for him to do it on his truck and would it be worth it to me to see if they make one for our application.

I found this one to http://www.jdsperformance.com/index....=item&inmake=0

I honestly don't see that big of a horsepower change especially for our trucks but I do think it's a good setup on the 5.4. I say let him buy it and see how he likes it.

I have a pro-m 75mm MAF. Its calibrated to my injectors and fuel mapping. *IF* done correctly, you will see GOOD gains down low.

On a stock engine.. I think you'd see more bang from your buck, with a set of underdrives or a tune/tuner.
