Ported Maf Ends And Tb...any Real Gains? Have you guys felt any real gains or seen any on the dyno from ported mass air ends and ported throttle body? are these two parts vital to getting max hp..or are we talking just a couple of horses? and also..who sells the best ported tb and mass air ends?

A ported TB is a great mod to do anytime. It's proven to gain about 5-10 hp whether the car is stock or modified. Gains will be greater the modified the rest of the engine is.
As for posted MAF ends, they are a usless mod that can do more harm than good. Here is some reading: https://ls1tech.com/forums/generation-iii-external-engine/121133-safe-mods-askin-pain.html

A ported TB is a proven mod. I recommend Shaner's TB's.
Now personally, and I'm sure lots of others will agree, MAF mods are pretty risky. Its hit or miss if you'll get any gains or just have problems. Most people end up seeing power loss from MAF mods. I recommend putting the money elsewhere as far as MAF ends go.

The TB is definately a worthwhile and proven mod, i sent mine to Bauer and he did a real nice job on it. 
Now for the MAF ends i would not recommend them. On A4 cars they are know to cause line pressure problems with the tranny, thus shortening the life span. The other problem you run in to is that the ported ends will most likely make you run lean, this happened on my car, AF was 14.7 
with the ends on. Just not worth the money in my opinion, ecspecially when the stockers are suffecient.

When I say hit or miss I mean you may or may not have problems with it. The power gains aren't good enough for me to spend my money on or risk the chance of issues. Something that is good to 450+RWHP has real no need to be touched.
Also they can be tuned, but its a bitch for the tuner.
