How's this ported TB look?
It's not bad but they could've removed more material that's for sure. Stay away from the epoxy. It marginally (if at all) helps airflow and if that little piece lets loose do you really want it flying past one of your valves and into a cylinder? Oh and your sig says you have an H and an X pipe...how does that work?
Wow someone sounds a little overly confident. I'm sure it would help at least a little bit to open up the front a little bit (there's a good amount of metal left right where the intake tube mounts). Doing this, cutting the bolts down to be flush along with knife-edging the blade WILL help. Now it may or may not be significant but that's another story.

Im not overly confident in the least... I have simply ported THOUSANDS of throttlebodies and I have dyno tested ALL of the options... Knife edging/epoxy/removing half of the shaft etc etc... Removing more material from the TB can cause issues with high idle and has not shown ANY gains in throttle response or horsepower.

For one its filthy... The shaft should be cut in half. I look at it this way. IT lets in more air, it cant hurt. It doesnt look like much material was actually taken out. The face of the TB shoulda been knife edged as well....
But hey if it works **** it.
