I exclusively use a small 25,000 RPM 1/4 air die grinder supplied via a 54 CFM 2-stage air compressor and carbide rotary grinding bits.

I would not use an angle grinder. That is asking for trouble... they are too big for the delicate work of porting.

I've been playing around with streetporting and have been very happy with a combination of a 1/4" die grinder with some 6" double-cut carbide burrs I bought on ebay from user mm_tools8rx7 (He was slow as hell about shipping, but the price was right and the bits are nice!) and an old multi-speed Dremel with fine carbide burrs. I use the die grinder for all my runner work and rough port shaping and use the Dremel for the fine work at the edge of the port. The die grinder cuts plenty fast, but it's really easy to go too far on the port opening. With the Dremel, I can shave off as little as a few thousandths at a time. Whatever you do, don't bother with any kind of grinding stones. The carbide burrs may be spendier, but they cut much more quickly and leave a much nicer finish.

I use an electric die grinder made by Jepson. It looks like a larger Dremel. I personally hate air grinders due to their sound, and the fact that I don't have a compressor.

As for the use of stones, I quite like them. I do all the rough work with stones, then finish off with paper sanding rolls.

I ported my waste gate with a Dremel & a carbide burr.
It was just what I happened to have.
It took about an hour.

The 1st time I ported a wastegate I did it with a dremmel, and a combination carbide bits and grinding stones.. It worked pretty well, but was slow and tedious. I now use air tool, and like them alot more.

Sweet! It's available from Harbor Freight for $15. I'm absolutely getting one for detail work. No more Dremel for me! Thanks for sharing...
