Updated Renntech Tune
Got a call from the folks at Renntech and they mentioned they have an updated tune for the V8TT that makes more power than the old one. Anyone heard anything about figures? I have their old tune and was curious. I've seen a number of tunes making more rwhp than theirs so an update would make sense. Apparently the update isn't free though.

"Our ECU tune offers the biggest performance gains on the market with our dyno results increasing performance from 556 HP and 550 lb/ft torque, to an astonishing 669 HP and 734 lb/ft at the crank! This allows the CLS 63 to run the quarter mile on D.O.T. street tires in an impressive 11.3 seconds at 125 mph with 0-60 mph coming in a mere 3.4 seconds."
I have it and love it but like I said on my other post, the stock continentals can't handle the power.

That marketing blurb is from their original tune. They say they have something newer and better. I didn't get any details on exactly how much better when they called. I got distracted talking about LSD and cooling.

The only thing that I have seen on this forum is that they can now disable the ECO feature. I got my ECU back from Renntech recently so I'd be curious as to what you find out.
