DIY tb Port? Well my car has just about every bolt on.
KN,LID,smoothBellows,SLP Maf,headers, ory, exhaust.
The suspension is done for the most part as well.
I have looked at my tb and realized i could probably port it a little bit myself and get some gains. Has anyone done this and is there any guides? Any gains to be made here? I don't want to spend money on an aftermarket tb atm so diy will have to do.
Yes i did search, saw some posts but nothing informative.

its not the best craftsmanship i've ever seen, but it is something i definately learned from. the next time i do it, it will be alot better.
the car seems to accelerate off of idle alittle quicker, but i haven't gotten a chance to run it through the gears yet... we'll see on thursday when i take it to the track.

And if you do go too far, just keep an eye out on the for sale forum for a replacement. 
I did one the other night.............. 10 minutes to take it off, 20 minutes to completely dissasemble it and port it, do the half shaft mod, bump stop mod, put it back together and back on the car.......... even trimmed down the EGR tube while it was off.
Unless you just don't have the tools to port it yourself, you're just thowing money away paying someone else to do it (and shipping both ways)
And while the polished to look like chrome inside may look pretty, it is all but unmeasurable on a flow bench and will not give a performance gain.......... as long as you grind it smooth and nice and even your work out, you are fine performance wise.

It takes me 45 minutes in just porting time on the TB housing, not including tear down or assembly or the other mods I did when I ported. Then again, I ported a couple of TBs for guys that did their own cylinder heads.....no names will be given 
BTW, thanx again fellas
