Hey truckin, you say he opened it up to 85mm. is that at the butterfly plate as well? Did he install a larger Plate too so there isn't a gap around the edges from a "smaller butterfly plate".
If not did you notice any high idle issue's? or does it fix itself?

 

I'll see about getting a video, just gotta find a place to do it since they closed off the old runway I use to go out to.

Weed - The screws are the most difficult part of getting the plate out, they are really soft metal and strip really easy. I could not get mine out of my stock TB which is why I sent the ported TB back so he could do it and not ruin it. As far as the bore, 85mm is what he reccomends unless you are going with PP heads then he would bore it to a straight through 85mm. and even then the the sidewalls on the TB are really thin. I dont think you could get another 5mm out of it.

 

Well he basically said that there were a lot of people that were having the same problems I was having and that it was a toss up on if it work for one person and not for another, no idea why though.

If he will still do the knife edge it be something to try, I risked it to see what it would do and it had some good points and some bad ones. Just be aware that if it does throw a code like mine did the truck wont run all that great and jump around at idle, 500rpms-1500rpms back and forth til it levels out. Mine also never showed a CEL, but doing the key trick brought up a code and using a scanner brought up the code too.

As far as returning it, I just had to pay the shipping to and from, which was all of about $28. I sent it to him last thursday and got it back wednesday.

Its a tapered bore, not a straight through bore. It starts at the leading edge of the butterfly plate and tapers out to the front of the TB. You can see it in the pics. I am not sure if it is opened up any around the plate though, but the angle the plate is possitioned is slightly more open than the stock plate.

As far as idle issues, it goes up to about 900rpm for an instant and then drops down to around 600rpms hich is where it usually is.

 

Actually after looking back at the pics I'm almost possitive that it is opened up some around the plate, dont have a mic to check by how much though or I would.

 

I had a fastman TB on my old Durango with the 5.2. It made a good difference. I didn't know Dan "the fastman" did the HEMI TBs its not even listed on his site:
