74mm Throttle Body Upgrade

Midrange from about 3200 rpm on up to around 5000 is simply beasty as compared to before. Wondering now if the larger TVT injectors will help out the low end 

Problem! throttle reset is not coming (as a thread tittle) up on the search! I don't have the time to read every thing in there. Can some one post the instructions here? You know as part of the instal steps
Here ya go Paul
Throttle Reset Procedure
Turn the key to the on (not start) position, the position just before the starter turns over.
Press the gas pedal to the floor with the key in the "on" position.
Hold the pedal to the floor for five seconds, then turn the key back
to the "off" position (don't remove the key), then release the gas
pedal.
Wait 2 mins. for a full alignment.
Drive the car as you always do.
Key on, pedal down, 5 sec, key off pedal up, wait 2 minutes.
Keep the key in the entire time.

Thank you Stogey! I actually did not think that Sprint booster owners needed to reset the TR. But since it take 3 min to do it I gave that I try. I don't know at this point if the bigger TB is helping any. Its ben 92 here etc... How about you guys?

My car is nowhere modded as heavy as yours and the gain from the TB and CAI tho modest, it's definetly noticable.
Dude it's been in the 90's all week, we're not that far down the road from Waco !

OK, so join me at a car show or something soon alright?
TVT guys I noticed you did not have a good picture of the TB so here it is, I just put it up on my site as well (feel free to use it as you wish):

Something is odd about that picture. The butterfly valve looks like it offset to the bottom of the pic in the TB. Note what looks like a taper seat at the top edge of the valve.
Question: Does that TB really have a large opening that tapers down right at the butterfly like it looks? Or is it just an optical illusion?
Sorry, it just looks off to me.

The picture is deceiving, but no.....the throat is not tapered. It's just has more of a polished look down near the butterfly.
Does anyone have the Mercedes and Bosch reference number off the TVT 74 mm TB?
I looked at my stock TB this weekend and measured the opening at ~3" = 75 mm.......however it is narrower at the plate and looks like it could be machined down to the same size as the opening and fitted with a 74mm plate......
Maybe TVT can tell us whether he is selling a Mercedes TB (p/n would be helpful) or machining stock TBs?

I believe that the opening is around 68 MM stock but can be machined to 74 MM. When I went to order my TB TVT had already run out of available units for sale (That's what I get for not pulling the trigger when I first thought about it). However I went a different direction and got one that has been machined to 74MM by AMS from over on MBW.
I worked with Omey (AMS Owner) to get mine but I think even his supply has dried up as well; hence Anthony's "Most Wanted" statement. The AMS route was a bit more expensive than TVT but I did not want to go without (I'm selfish that way)
. If you would like I can take a look and give you the casting number on my AMS unit if you think that will help...
I can tell you that I am still holding onto my stock TB waiting for some other "Goodies" so I know of at least one stock TB that will be available to be modified from AMS soon.
Stay Safe...

Just get one for an 05 S500.
The 08 E350 will fit as it is the same as the one on our engine, size and all.
Next time we get one in we'll get the part number, we just never have them in for longer then an hour or so.
