The graph just looks like somebody put a stiffer wastegate spring in an already choked out turbo. Note how the before and after graphs come back together at the top side. I'm sure the extra torque is fun, but I wouldn't call this impressive. This just looks like someone took the "warranty wiggle room" out of the stock settings.

Nothing was physically changed on the car. The TB, Air box and stock exhaust are restricting the car from making any more power. The stock turbos run around 22-25psi.
In stock for the car runs 11.5 at 122 weighing 5023lbs. Hopefully this will get him close to the 10's.

Mike, I was there for the dyno session, but can't take credit for the tune. Jerry Thornton from Eurocharged (LET) in Chicago e-mailed the tunes to the client's laptop which was uploaded to the software that LET uses for MB tuning. It's a very similar arrangement to your CMR software. Log the dyno or road file, then e-mail the logs to the tuner who is off-site, then the tuner sends the revised calibration via e-mail to the client (just like we do with Diablosport CMR). The client loads the tune into his handheld programmer (like the Predator) and then reflashes the vehicle. I believe the program is from Germany. I wish you guys had some CMR software for the MB vehicles as I would be all over tuning them. For this session, I was just a spectator.
We do have big plans that include many of the popular Euro applications, and when it happens, we plan to make a big splash in that market. Keep an eye out...

At certain points the car makes an extra 200 pounds of torque. What does it matter if it comes back together at the top side?
200 POUNDS OF TORQUE from a tune!!!

Say whatever you want about German cars, but you have to give Mercedes Benz credit for offering a line of V12 twin turbo cars to the general public. And boy, do they respond to a tune.
Stock hp and torque are in the dotted lines:
531rwhp and 688 rwtq bone stock. All in a 4800 lb 4 door sedan.
After a laptop tune (still stock intake, exhaust):
582 rwhp, 840 rwtq. The dip after torque peak is wheel spin on the chassis dyno. Just be careful when picking on some unassuming 4 door Benz. You might see tail lights.

WOW! What has it ran?

This doesn't surprise me considering the hp/tq gains the euro's get out of bumping the boost in turbo'd 2.0L motors. The saab, audi, vw guys see upwards of 70ft/lbs of torque and 40-50hp with just a tune upgrade. Granted, they go from the factory 11-12psi of boost to 16psi, but it's quite a noticable change.
So I can totally see the upgrade has on a v-12 with twin turbos that spool up quickly.
Quite impressive. Maybe someday, when the kids college is paid off, I gotta get em out of daycare first.

wow. id say its damn impressive. is the customer planning for any mods, or just gonna stick with this almighty torque monster? on a side note, look at the guy's previous cars...
anyone ever got ahold of a Brabus car? the torque has to be limited on some of those cars according to Top Gear, so id love to see a modded one of those...

Yep...these cars are impressive. Mine is a CL600 and went 12.29 @ 115 with a 1.97 60' on BFG G-force all seasons with a ~3900' DA this past weekend. The difference in the 600s and 65s are primarily in displacement (5.5L vs 6.0L).

About 5-6 yrs ago a guy brought a dampner into a machine shop i worked at and asked us if we could fix it. It was for a benz sedan with a supercharger from the factory. He was installing it and trashed the keyway bad. My boss said yeah it won't be cheap, he said it was $5,000 we almost **** ourselves! So we welded tigged it up and rebroached the key for like $300-$400. I think it added like 4-5lbs of boost and came with some new tune you installed yourself or something. That did not include any dynoing.
