SL-65 Dyno Results
Casper356, I, like Schiznick, thought RennTech only modified the shift points of the transmission via the TCM and this mod was a part of the ECU upgrade package with a cost of $6400. If RennTech is rebuilding the trans to handle the increase in torque what are they charging?
Also, can someone speak to how the suspension of the SL 600 compares to the AMG suspension? Can the OEM springs and shocks of the 600 be replaced with after market components resulting in a vehicle that rides and handles similar to that of a SL AMG? I realize you can lower the vehicle via a lowering module but to obtain the ride and handling characteristics of a SL AMG, I would think you would have to change the springs and shocks also.
I apologize for the long post.

Unfortunatly im not to familiar with the SL600 handling but from people I have spoke to on it at Mercedes, They said SL600 is more of a stock type suspension where SL65 would be more considered a racing suspension thats more stiff and can handle turns better.
Edit: Just called on Pricing info for the Trans upgrade - $1300.00 Parts - $2000 for shipping to and from Florida and about $2000 for the Labor

Since the ECU mod supposedly can't be seen by the dealer it doesn't seem to effect the factory warranty but I am sure the airbox is very different. Will something like this give the dealer an easy "out" on the factory warranty if something actually did happen?

SL-65 Amg actually has a 0-60 in 3.8, Mercedes has a nice habit of making there 0-60 times seem slower then what they really are.
To the one who asked about the warrenty aspects, Renntech has a contract with Mercedes which allows for the mods to be placed on the car without voiding the warrenty. Any other Companies that offer mods for mercedes however would void the warrenties.

Where did you hear about this agreement with Mercedes so that it does not void your warranty?
Sounds like Salesman speak to me, no way!
That does not mean that Renntech doen not have their own warranty and I believe they do. As with any mod, it will only potentially void the warranty if the part changed influenced the failure. If you tune your ECU and the command fails no problem.
If Mercedes can point to a Renntech part as a potential influencer of a failure good luck getting them to cover it.
If you have your ECU tuned and you blow up your transmission or differential you will be in trouble........

I agree. Don't believe the hype folks. If you have a trans. or serious engine problem and take your car to your local MB dealer and you have visible Renntech mods on the engine there is no way they will cover it. MB has nothing to gain by spending money on an engine failure tuned by another company. Now if you buy from an MB dealer that actually sells and installs this stuff and gives you in writing that you are covered you would be good to go but don't expect other dealerships to honnor this agreement.

Well the information that i got was from Renntech, the local Mercedes Dealership here and the Corporate Offices for Mercedes. As long as it was installed by a authorized Renntech dealer with certified installers it does not void you warrenty.
Now to clarify you can also check on various other companies that have contracts with certain companies for upgrades.. Here is a few examples for you. Which these companies upgrades will not void your warrenty if the installation is done by authorized installers
Ford - Saleen
Nissan - Nismo
Dodge - Mopar

I was not saying that it will totally void your Mercedes warranty. What I am saying is that if you have a failure that appears to stem from a modification done by your certified Renntech dealership then Mercedes (MBUSA) will not cover those parts under warranty.
I just called MBUSA and they said no way. I talked to three people and got the same response.
Here is the jist of my discussion.
Renntech is not affiliated with MBUSA or AMG in any way. Some Mercedes dealers are also Renntech dealers. Mercedes does not warranty any Renntech parts.
If a Renntech part causes a failure, in MBUSA's minds it is the owners responsibility to resolve the issue . The Mercedes warranty does not cover any modifications to the car by a third party vendor.
They also said that Renntech may have their own warranty to cover failures and that the MB dealerships that install Renntech components may have alternative programs.
It was mentioned to me that if you expect your dealership to warranty Renntech equipment they put on the car you better get something in writing from them that the dealership will provide the warranty because MBUSA will NOT pay for repairs under warranty that result from a tuners modifications.
Let me say, I have no problem with Renntech at all and am considering ECU tuning for my SL65. I just don't want people to get a false sense of security that these changes are covered under you MB warranty.
If you want to play just be prepared to pay!
Enjoy!

ok maybe you miss understood me... yea they dont cover Renntech parts, but having the items on there does not void your mercedes warrenty. Renntech parts are warrentied by Renntech.
And yea there are always situations that can void your warrenty anyways... IE misuse of the car, like drag racing
