You are the 1st 03 that I've seen on this site. Well, I've seen others, but no one else has talked about running them hard or anything.

I am no expert but with a fully stock motor I have heard MANY times the the Granatelli MAF does nothing but lean things out and cause problems. Might want to put that expensive piece off to the side. :-)

The problem lies with using the GMAF with other mods such as HPP3 b/c both will lean out the truck too much.

It seems kinda early for Granatelli to already have a maf for the 03's. You sure it's not for an 02? Not many other aftermarket companies have rated their stuff for the 03's yet, although a few have. I don't see anything on Granatelli's website about a maf for the 03 trucks.
