looking to start building an FBO E350. if anyone has a link to headers (i know of supersprint's) please send them. any links to bigger fuel injectors, link to a big camshaft, and any reputable tuning shops. preferably near florida or maryland. also does an E63 AMG of my same year have a better intake manifold/ air intake? if so, is it just a swap?

 

As someone who has an e350 and has been trying to find some power-adding mods, there is not a lot of aftermarket support out there. You’ll end up spending 2k on custom headers, another 2500 for a catback, etc. If you’re looking to put money into your benz, sell it and get an e550. 2k tune from Renntech bumps it from 400hp/400tq to 500+hp/700tq.

My E350 is tuned, only big thing is the removed speed limiter (and burbles)

 

Burbles, eh? How much did that run you?

 

I would love to "tune' my E350, who did yours and how much horsepower gain?

 

My tune was from OETuning, and in total was 650. That included the handheld tuner and tune.

 

I did mine thru OETuning, they claim about 30hp. Being a naturally aspirated engine, there isn't a whole lot of power gain. I mainly did it for the removed speed limiter (This car is capable of 160mph+), throttle response, and burbles.

This is a pull (in Mexico), where I have one muffler (of the two) off, with the burble tune.

My car is currently straight piped as I am in the process of installing an x-pipe in place of the resonator. Its too loud for me, but I've been fooling around a bit until I get the chance to install the x-pipe (hopefully this weekend).
These are the burbles with that

I do want to add that OETuning is pretty hard to reach after a month or so of purchasing your tune. I was looking to have my speedo uncapped (it stops at 160), and they never responded to my e-mail.
Tune works good and also allows you to flash back to stock tune
