Default Need Some Answers?

So i have the Professional Product Intake Manifold and Accufab 70 MM throtle body and Plenum. I havnt put them on the car just yet because i put it away for winter....but i wanted to know if i need a 90MM MAF then tune for these? and if i should upgrade for a 75MM TB because of the Intake manifold or if you guys think i should just sell the intake manifold and just port the heads for the cam?
Im also planing on going with Trick Flow Mild cams, and i was wondering if i added trick flow mild cams in there with the intake manifold and TB and plenum if i would need a MAF and possibly fuel upgrades? Throw me some opinions!

You don't need a new MAF or tune for the parts you have. With cams, yes you'll need a tune.

If i get Steeda to tune the SCT X3 for the cams would that be enough? the SCT is already tuned for the intake mani and throtle body and plenum etc...

A custom SCT tune for the cams should be fine. The intake manifold is only good if you can take advantage of it. In other words, if the Trick Flow cams can spin high enough to take advantage of this intake, then it's a benefit. If not, then there is a chance you'll be loosing power...especially in the low and midrange.

You'll probably have to upgrade your injectors though.

^^+1..... Unless you have a lot of boost (along with heads and cams) or plan on spending lots of time spinning around 6000rpm, aftermarket lower intakes will hurt your power.

Sell the intake. Its junk. Friend lost power with it on his nitrous car. You dont need to upgrade anything but possibly injectors for your setup with the cams. Ported heads and mild cams will put you right around 300rwhp or maybe a bit better. That would be your best bet to go with. But get rid of that intake manifold.

Im planning on going with Fox lake stage 1 heads and comp cams, Steeda UDP's, 42 ib Injectors.
Would i need the MAF with the heads or just injectors? and possibly fuel pump?
