    Need help with MAF and Throttle Body

    I want to add MAF and a Throttle body to my current setup. I don't know what the hell I'm doing, that's why I enjoy spending time with you guys so much. Please help me out with a good setup. I am running the stock injectors, should I upgrade my injectors. Any and all information is helpful. Thanks, you guys are great!

    With a MAF mod I think you need to upgrade the fuel injectors. It should say what size is to be used with what size MAF sensor. As far as the throttle body goes, it should just be a simple bolt on mod.

    They are both simple bolt ons, but don't add much to a non forced induction car. The MAF is calibrated to the injectors...so unless you get a MAF calibrated for different size injectors than your stock size, you'll be fine.

    This is probably a stupid question, but if the shoe fits. What are the stock injectors?

    Cool stock injectors

    They are 19's as for new maf and injectors unless you do some heavy modding like pnp heads and cams not really a worth while mod.If you plann on doing others such as power adder some kits upgrade these as part of the package so make sure of your future plans.So as not to be throwing good money away.

    Thanks! What about the throttle body, is it worth while?

    A lot of people say no, but I felt the FRPP/SVO one provided a cleaner, more accurate representation of what the pedal was doing, therefore seems a little more responsive...as far as more HP, I wouldn't expect any out of it.
