What kind of dyne are you using? Have any other cars dyne's for comparison?
Your numbers are very peculiar. And I'm not even talking about the super random 17% figure you're using for DTL.

Doesn't matter for most people west of the Mississippi anyhow, since they are pretty clear the tune cannot be run on 91 octane.

Most important are the power gains at the wheel. Which we show in our Dynograph.
For customers that want to compare the performance numbers to stock numbers, we provide crank horespower numbers, since Mercedes-Benz only publishes power at the crank.
We use a 17% drivetrain loss on 4MATIC vehicles, based on years of experience in testing Mercedes-Benz vehicles.
For customers that only have access to 91 Octane fuel, we have second upgrade option:

Also, do you feel it is safe or unsafe to push pass the performance levels of your tune?

Right? I have NEVER heard of anyone going below 20%. I want to hear the reasoning and not just some BS answer like "because of our years of experience blah blah blah..." c'mon guys.
Your dyno numbers are sketchy if you ask me.
Every other tuner is showing MUCH different whp numbers for the stock car; hell, some companies are showing less whp on their tune than you guys are measuring stock. You guys are a trusted company, at least I assume so for how long you've been in business, but this screams scam job to me...

Audi fanboy here. I chose the 450 since the B8 S4 is dead and the B9 isn't out yet, but I gotta say, I think this Merc is changing my brand loyalty a bit. If they introduce the C63 with 4matic by the time this lease is up, I don't think I'm going to be going back to Audi anytime soon

Hey OT real quick, I don't see a current car listed in your stable. You whipping any Audi's these days?

So I arrive to now and I'm digging the new MB's as I don't like the interiors of the newer Audi's, something just seems too cold but are great, techy and edgy. As I have analyzed this; I realize I'm getting older and I think this is playing a roll now as the MB interior is just more comfortable for me.
So I'm on the fence about a C63 or C43. I have test driven both but not back to back. I want the V8 but want the AWD. Great problem to have tho. I think I will be back at Audi because my fiancé likes the them so her next car will likely be one.
Okay rant over.

What is the drivetrain loss on mct 4-matic, renntech?
#15
Yup that's what community looked like I didn't see many issues. However, for me it would have been like getting into a slightly smaller S5 interior lol.

I currently don't have a ride. We are buying a house so we use my fiancées car. I was a major Audi fan. For the north east; they are superb all weather vehicles and I'm sure you know that. The A4's got me through some of the worse winter storms here in New York. Had winter tires on the S5; it was unstoppable. I gave the Q7 to my X but it was sweet for what it was. That thing crushed in winter and was solid (300 shy of 6000lbs). The performance was good but always struggled with the understeer even with changing the entire suspension. However, non of those reasons was why I didn't get another one; I just wanted to try something different. So enter the Ghibli ( Mistake) after all the glamour wears off your stuck with great handing piece of tin. It was not put together well.

And even though the B8.5 is a nice car, I'd hate seeing the B9 come out in just a few months. If I'm going to spend the money, I want the new new.
My car struggles from time to time to maintain traction (especially so when the tires are cold) even with the AWD. I can't imagine what it's like to try to constantly wrangle the back end of the 63. I would have LOOOOVED the V8, but RWD just isn't feasible for me.
I really want to find a local c63/c63s and do some highway pulls. I know I would walk one from a standstill but I want to see if the top end is in my favor now. [Que c63 fanboys in 5..4..3.......]

I don't necessarily hate the s/c V6, but I don't really like it. I like the efficiency of turbo's compared to a blower any day.

Ah right on time boys lol
I stated that as I am not stock and am SIGNIFICANTLY faster than stock. I should know, I drove this car in stock form for 3 months
Conclusion: I make equal hp and more tq than the stock 4.0T. I have more DTL, but I weigh 200lbs less so....
There is only one way to find out

I just wonder why Renntech is so much different than AMR and vice versa; in relation to these tunes.

This seems to come to my mind a lot. However, the small voice says " it will never sound like a V8'. There is something really wrong with us all . Just this morning i was thinking "it will be fine with winter tires?".

So you are saying that the c43 will make faster 1/4 mile passes?
