TPI intake base porting
Who does intake porting? I'm looking for a mild port job. Just to clean it up, and not make the walls too thin. Don't want to create vacuum leaks. Just a mild clean up port.

You can do it yourself if you are cautious and get a die grinder and some carbide Al bits, flap wheels and sanding rolls plus some dividers. Easier with an air die grinder that can control the speed if you use long shaft carbide bits to get deep in the manifold runners. You'll need it to get to the middle of the runners along with long sanding rolls. An extended nose die grinder helps too. Do some research first and understand what MCSA you are looking for. Keep a vacuum around to suck up all the aluminum chips and use a face mask to keep the particulate out of your body.
Not a lot of fun but you can do it if you have some patience.

FFI does some AWESOME porting. They can set you up with a TPI so big, you can drive a truck through the tubes!

I 2nd porting it yourself. I've done several TPI intakes now. You'll need a set of long shank single flute burr's. Also Harbor freight sells this awesome sanding roll kit with a very long shank on the paper holder.. It works really well for reaching in there.
But if you don't have the time or the patience, then I believe Fasterproms is still doing intake porting. At least they show that they were porting customer intakes on there YouTube channel about a year ago. I would give them a call.

I agree. I used a combination of wire wheels, burrs, and flap sanding. I put them on a long extention (with a 1/4" shank receiver)...though my burr has it's own 6" shank. I didn't even use any air-powered tools - like a die grinder. I used a 2k rpm drill. Burnt the **** up by the time I was done, but that's OK. Can't say I ever want to port another intake though! LOL
Also as far as tools go I found the Harbor Freight small straight die grinder works really well for porting anything aluminum. The thing was only $10 and worked great until I dropped it and it broke.
