I've been throwing around the idea of getting several parts for my 2004 Silverado LS to improve gas mileage while boosing power. Here are some of the parts, give me your opinion on if they would be worth it or not.

negative, both are a waste of time and money. aftermarket MAF sensors do nothing.
on 96+ trucks throttle body spacers do nothing, there is no air and fuel mixes at the throttle body for it to help improve, like on the old tbi trucks.

best thing would be a custom tune by nelson performance or blackbear performance with 80% of your torque management removed.

i haven't seen any of these gimmick's work yet in the real world ,if you do religiously check your mileage .
