Going Renntech for the following reasons
I have finally decided to go with Renntech ECU, Pulley and headers for the following reasons. BTW, thanks GID E Up for the pics of the stock headers. I can't believe Mercedes Benz put that sh** on my car...
https://mbworld.org/forums/showthrea...hlight=headers
1) Install can be done by a dealer - I am having my install done by a dealer in NY. Check out Renntech's website. A lot of their dealer locations are actually Mercedes Benz dealers. I am taking my car in for the 1,000 mile free service and while that is getting done I can get my Renntech installed. They are even going to give me a loner car. Possibly a Renntech MB.
2) Doesn't void the warranty - A Mercedes Benz dealer can do the install that will standby the warranty. What more could you ask for.
3)Renntech is extremely helpful. - I spent at least an hour talking to George Leca at Renntech. He explained all the parts and packages that Renntech offers for my car. Very helpful and insightful.
4)Renntech ECU & Pulley could be faster than Kleemann ECU and pulley. Check out SGC's E55 without headers. I will admit Kleemann headers look awesome, but they remove the cats and the 02 sensors. With Renntech you keep your 02 sensors and primary cats. In addition they are bolt-ons, so there is no welding.....
I am getting my car done on Saturday, and I will definitely let the group know what I think of the Renntech upgrade. If I am heading down the wrong path, or my analysis is wrong, SOMEONE PLEASE TELL ME.....

Nothing wrong with which tuner you choose however some of those stuff you mentioned for example like "Install can be done by the dealer..." If you look at the Kleemanns website they also offer the same thing. They have a lot of Network of Kleemann authorized dealers as well and can perform the same installation. But like what i said i guess it's just a matter of convenience. But nonetheless RennTech is

I like that fact that the headers are bolt on and you keep your o2 sensors and cats, and if the dealer will honor the warranty, how can you beat that? Any idea what the total cost will be, and what do expect for HP and TQ gains?
Thanks

Congrats and I hope they do a fine job. I can't imagine what could be wrong with Mods with a warranty. I might check out MB of sugarland, TX. They are the closest MB dealer who is either a RENNtech or Kleemann dealer. Ricky, know anything about them?
Let us know it works out.

MB Steve,
Glad you came to a decision. I thought you were going to explode the last couple of days. You were obviously anxious, and this decision weighed heavy on your mind. I know................... I went through the same thing.
You know what? I like Renntech too. I purchased their rear spoiler.
One final suggestion, show us some track numbers. Dynos are fine but they are not a true measure of "street" performance gains.

If the MB dealer is a authorized Renntech or Kleemann dealer you should not have any issues

Renntech performance package 3 is $9,695 on their website. Website says it will give you a 75 horsepower gain and an 80Ib-ft. torque gain..

In most cases you are correct. However, if the failure is major, such as a blown engine, you'll be dealing with a regional Mercedes rep and it won't be the dealers call.
I modify everything that I own so I say go for it! However, be aware that there are risks. Renntech is a very reputable company and the odds are that you won't have any issues. Good luck and have fun!

By any chance where you there last Friday night discussing the mods? I was picking up my car from service and overheard a salesman talking about adding Renntech mods.
I do believe that they can adjust the timing and fuel curve through STAR DIAG, but I dont think they have a dyno for HP. I could be wrong about the STAR DIAG though.
Good luck with the mods, you picked a great dealership. BTW: very jealous of all you E55 owners! By far my favorite sedan.

Oh ok, the new location is nice. BIG! I havent had to wait there though since they moved so I havent had a chance to take advantage of what they have there. I dont know about the Renntech shop, but they may, they are supposed to have 41 work bays, so to have one of those for Renntech is possible.
