Mass air meter? Keep it?

Just got a new lid for my 2000 trans am, but was wondering if I need my mass air meter or not? I know need the sensor but what about the massive silver box half way to the throttle body? Keep it or not? I've seen some with and some with out.

Yes you need it. Don't de-blade it, don't de-screen it, and don't port it.

Ok. Just curious. You know where I can get som rubber tubing to fit around the lid to run to it??

Go to a hardware store and buy a Fernco coupling -- I assume they have similar stuff over your way. You shouldn't need any additional parts though to install the new lid. What exactly did you purchase?

Granatelli lid, picked it up off eBay

If this is what you purchased: Granatelli Air Lid Then you should not need anything else. The neck on the lid will mount to your existing intake tract and delete the helmholtz resonator.

Yeah I kinda pieced that one together last night. It doesn't seal very well, electrical tape? And the front corners of the box have a gap too. Maybe some silicone sealant? Overall, big increase in throttle response! Little bit more kick. Horrible fitment. But not bad at all for 30 bucks

The reason you see some people (like me) without it, is because we have a different type of tune that relies on the MAP (Manifold Absolute Pressure) Sensor instead of the Mass Air Flow (MAF) Sensor. It's called a Speed Density Tune. I love it, but unless you're going in for a tune anyway, I would not spend the $300 for a SD Tune on a stock car.
