    Default Questions of modifications.

    I rely on the opinions of the members of this site quite often. I read the forums everyday and have gained much valuable information. But there are a few things that I question. In researching future mods for my truck I have come across conflicting information.

    Throttle Body Spacers: Some people swear by them, some say it's a waste of money. Just read on another forum that a guy picked up .2 in the 1/4 with just a TB spacer.

    Aftermarket MAF sensor: Same deal, had a guy on here tell me it was a waste of money, and have read elsewhere that people have picked up power and mileage.

    Aftermarket Throttle Body: About identical to MAF, read on here where it was a waste, but elsewhere read that it benefitted others by power and mileage.

    I realize different vehicles respond differently to mods, but to read 2 completely different views on the same item seams odd. What gives?

    TBS - Unless you have $90 to throw away I'd say its not worth it. I picked up slightly better throttle response

    MAS - If you couple that with a new CAI that will allow the engine to breath better and would give you pretty good bang for your buck.

    I have no idea about a new throttle body.
