That is just an amazing time for an SL600 w/ those mods. Very nice to see such a quick SL.

Come East near the water and there's no less than 3 SL65's and 7 SL55's within two blocks of me...and across the street there's another black RennTech SL600 and yet two more RennTech SL600's within a block (none have the V12 BiTurbo on the trunk) ...and yes, millions of SL500's. Yes, a few DB9's, two V12 Scaglietti's, a few 430 modena's, and a Porche GT, and few 911 Turbos...

I was the first SL600 to get the RennTech ECU and TCU upgrade back in '03 and haven't had any issues and still love to drive her everyday...

I raced a 2006 CL65 about 1 week ago. We raced three times. Twice from a roll and once from a stand still. From a 30mph roll we were dead even up to about 130mph untill we needed to brake. From a stand still I beat the CL mainly because of traction issues but it was still very close. I assume it would be about the same against an SL65 but I'm still looking!!!

Holy ****!!!
I wish I saw even half that many nice auto's around where I live. I'm in Soccer Mom-ville with SUV's everwhere and on a rare occations I see some 911's. I see a few nice cars at work. Actually a guy I work with got the first 2007 911TT in South Florida. He ordered it 1.5 years ago and got it for MSRP. I sat in it and rev'd the engine a bit. Very nice but the exhaust note is way too soft for a car of this caliber. No Keyless go on the Porsche! I know it's a true sports car but this is a feature I don't think I could ever not get again. Keeps me limited to Mercedes or BMW for now.

I love my SL600 also and use it for my daily driver. Wish I had the 65 though. Maybe some day.

Renntech,

What is the rt 98 octane fuel map? I did not know they had that. What will that do for my s600 ecu/tcu? Do you have to always run a high octane?

yes

If your tuner ... tunes your Ecu to be running on 98 that means you better be on 98+ all the time. Otherwise you might run risks of detonation.

I love the look of the SL65. What is the insurance for this car go for (1 year est...)?

I pay about $1800.00 / year for my SL600. Not sure if a 65 would be more or less? I'm assuming it would be about the same or a little bit more.

I am guessing Dyno comp did all your work. Did you add the airbox as well? What kind of gains from the airbox did you see? Do you have a sound clip of the exhuast?

No RT airbox, I'm running the stock one. The only clip of sound I have is from the track

That's damn fast for just the ECU and stock airbox! What did it dyno at, and how did your dyno compare to the one posted on Renntech's website?

Thanks in advance....

You should join us in ATL on November 4th and 5th. Then we can put the stock SL65 v Renntech SL600 questions to rest for a day or so : )

Come on up!

Thanks for the invite! Where and what is the ATL. If it is local I'll try my best to make it. Sounds like fun. I've never taken any car to a track but I have always wanted to.

I actually may not have my car in November. I've been trying to find a low mile CL65 and if I get a good deal I'm going to buy one. I'll post if I get rid of my SL for a CL.
