Renntech Bangs 548 Horsepower out of Mercedes C63 AMG:
Originally Posted by Worldcarfans
When Mercedes introduced the C63 AMG last year there was a lot of anticipation to get behind the wheel, but along with this anticipation came the disappointment of a power rating of just 451hp. An output like this is way below the E63's 507hp and S63's 518hp which both use the same engine, theories as to why the power output was reduced pointed towards the restrictions of getting the large 6.3 liter naturally aspirated V8 engine into a smaller engine bay but even the smaller CLK63 AMG managed to pump out 475hp.
Renntech set out to reverse these restrictions and give the C 63 a power figure to be proud of. An initial ECU software upgrade put the power up to a CLK63 matching 475hp until the tuner had more time to hammer out the engine a little more. This hammering has now been complete with an updated version of its ECU software, RENNtech's stainless-steel long-tube headers and new, track-oriented sound/performance pipes bringing the power figures up to 548 peak horsepower and 510 lb-ft of torque.
Renntech also found time to bang in a height adjustable suspension kit and a new stopping power enhancing braking system.
It'll be interesting to see what kind of performance figures the Renntech C63 is capable of should they decide to release them in the future, however Renntech do tease that an overpowered & 63 monster could make its way through their factory doors for their 20th anniversary celebrations.

MHP as we chatted - the chipping alone is $4000. Renn is nuts about that pricing with MHP coming out with his tune soon, Kleeman and Vadim at $1500 (still high in my book for a software load, but what do I know - I've been price shopping a GT500 for the past year before I bought the 63).
And the brakes, honestly - any of you feel like you're not getting enough braking? LOL. Stainless lines, yes - I'll take the pedal feel please. But replace the brakes on these cars? why bother?! These brakes rock!

And that's just for Headers and ECU. Those guys really have a screw loose.

Oh, and PS. If they're using 17.5% DT loss (they're probably using 20% to make themselves look better) to come up with the 548hp that would mean ~450rw. Wouldn't it be nice if you could hit that goal with just TCU/ECU tuning and filters, no headers?
