- Mercedes Benz E Class AMG: How to Install Throttle Body
Step by step instructions for do-it-yourself repairs
90mm Throttle Body install with parts/pics




Thanks for the info. Looks like I need to get a good custom tune .. thanks for justifying it


When I got my car, I never got over 19.x mpg. MBH headers and midsection added a lot. I drove it up to get tuned after installing them (before adding a TB, rail, injectors, etc) and I got around 23mpg driving up to LA. The ported heads with larger valves helped a lot, also.

I still cant figure this one out.
I took mine apart and slowly put it back together checking every seal.
@ Hawkins are you using an adapter plate or direct bolt on?
same question to you saleen01?
has anyone fixed this issue after having it?
most people I know go down to the 80
I guess I should start looking for an 80mm.




I have zero issues with the 82mm, I have also raised my base idle speed to the high limit. Driveability is the same as stock.
Good job on the 90mm, would love to see some dyno and track numbers!

Rolling eyes at you, SoCal!), it's hard to gauge how close or how far I am.I guess there's always bench racing!
But, I'm with Roverron in that I want to see this mysterious issue get solved. It can totally be lived with and "driven around", but seeing as how that and my rear O2 sensors still throwing codes are the only issues I am having with a car that is this modified, I can't complain too hard. It still eats when I feed it, lol.
I am not saying my car does not have it's quirks, it just does not have the hiccup. Trying to get a smooth idle with 1000cc injectors with our AWESOME ecu's is a task. It does not like idle or bumper to bumper traffic, but loves WOT and freeway cruising. Wonder how much this mod pics up over the 82mm.
My worry is one cost and two what if its the opposite and the later file is the issue.
I will look at going to dealer and if they will even do it.
Cant a tuner flash an ECU to stock?
I thought they kept stock files

That really looks almost stock to you?

The inlet was bored out a little before it was mated up to the 82mm. Right now the adapter tapers from the 90 to the 82, but that's only because I didn't want to pull off the supercharger to remove the snout. I don't have the garage space to do that kind of work for now. Eventually, I will pull it and I would like to come up with a better solution. Maybe cut the snout back, open it up to 90mm, and permanently fix the adapter to it (while opening that up to 90mm, too). This would give about an extra inch of space around the Y-pipe area. It is way too tight back there (What she said).
Exotic was just saying how nice and clean it all fits there. Maybe I'll get a nice AMG logo to put on that TB cap there. Hmmm....

In other news, dropped the hammer last night at 80mph and got the flashing triangle
