Got Weistec Tune & Weistec Filters on my 2012 CLS 63
OMG

All I can say is WOW!!! power band is opened up. Acceleration is fantastic. Shifting and throttle response is crisp. Why didn't MB do this from the start. According to Weistec, I am getting 620 RWHP or 725 HP at the crank!!!

Those are some pretty incredible numbers. That's about 55 more hp than Renntech ECU tune! That is significant.

Come on Renntech, what gives?

Congrates, those are some really good numbers.
There also working on turbo upgrades… Know that should produce some Serious HP!
I can’t wait to see that finished product.

How did they flash your tune? It seems like drilling a hole into the ECU for access is done by more than one tuner. Tell me they use a more stealth method.

We do not do drilling or any other permanent modification to the ECU.

Very Pleased with results AND still got 24.2 MPG

My car now has a BIPOLAR personality - calm for the wife and city...crazy for me and the city/freeway - lol

Obviously the power's there, but how is the overall driveability of the tune now that you've got some miles on it? Any hiccups anywhere?

Wow. Serious stuff. Would be great if you could post a dyno sheet so we can see how the power is distributed along the rpm range...or perhaps Weistec can post something.
