E550 BiTurbo Renntech question
Any of you guys out there with an E550 Coupe with the 4.6 BiTurbo Renntech Tune, what is the 0-60 time with the 540hp tune? I know that the car can do low 4's stock, so I would imagine it being somewhere in the 3's.

So I've hit a crossroads after reviewing the Renntech upgrade.
The 540HP that is quoted is actually for the crank. They say that there's a 14% drivetrain loss, meaning that the actual WHP is 465.
Which is now making me question whether or not to spend 2500$ for 60-70 more horsepower. RaceChip GTS Black offers 480 HP for just 800$. The question is whether or not the 480 HP is at the crank, or at the wheels.

Yes, all tuners (to my knowledge) advertise hp/tq numbers at the crank, just like all the car manufacturers do, not just because the numbers are higher that way, but also for consistency so that the public is not confused. If any advertised power number does not say "at the wheels" or "to the ground", you can safely assume that these numbers are the rating at the crank. Remember, the M278 was "conservatively rated" at 403hp by Mercedes, and most tuners have learned from stock dyno results that these engines were actually putting out around 430hp at the crank bone stock, so that Racechip 480hp is only adding 50hp for your $800. The 540hp that the Renntech tune provides is the highest HP number of any tuner for the M278 engine, with Eurocharged at 530hp and on down from there. While the HP rating is important, what you must also consider is the torque rating. Renntech offers the highest torque output for the M278 engine at an immense 705, which it is still 606 at the rear wheels! This is on par with a Renntech tuned V12TT. My old CL600 that was tuned by Renntech had 625hp and 735 torque, but the car was probably 600+lbs heavier than an E550. No other tuner offers over 600 torque at the wheels with an M278. This is one of the reasons Renntech commands a premium for their tune, as it is a "premium" level tune. Just like with so many things in this world, you get what you pay for.

Probably going to stick with Renntech. I’m confirming with Eurocharged that their numbers are at the crank as well, and Weistec is out simply because they require you to buy their spark plugs for the tune.

we have a pretty stout 4th sale on the handheld and tune if anyone is interested. We are typically over 1k less that RT

I sent you guys an email regarding the tune last night. I am curious as to whether or not the 530 HP and 606 LB FT are at the wheel, or at the crank. If it's at the crank, then Renntech offers a lot more torque, which is going to sway me from Eurocharged.

We have some really great 157 278 product offerings, Most dont think of us for those cars but we are pushing into that platform much harder now.
Superflo pump is a really great cooling upgrade for those cars aswell,

I estimate the 0-60 times somewhere in the 3's, seeing as how the car already gets it into the low 4s.

In order to get more HP out of the car, the boost is upped, thus TQ is substantially increased. Our stock trans has a limit of 516, RTs torque figure is something like 700 right? That's almost a 40 percent increase in torque over the limit of the trans. If all that TQ is applied at 100 percent in first gear, there's a very good chance you'll grenade your tranny of diff, and on top of that 60 happens the end of second gear, so if boost is limited the first and second gears, your 0-60 won't improve.I believe it was actually a thread RT had created advertising their tune, where someone chimed in saying that boost is limited, however they were driving a 4matic model, maybe that was the difference? I'm trying to look for the thread now to link it.
I still stick with my claim that the 0-60 will be greatly improved. I watched a video of an acceleration (There was no timing and you couldn't see the speedometers) from low speeds and you could tell that the car was pulling a lot more than stock.
Either way, I'm probably going to go with the turbo upgrades that the person mentioned in this forum, as they offer 600WHP+.

Aha! I found something. This proves that Renntech upgrades will increase your 0-60 times. The CLS63 has a stock 0-60 of 3.9 seconds. 2012 model year. Renntech states that their tune pushed the car to a 0-60 of 3.4 seconds.
