C450 AMG
A) bump, has anyone purchased this tune for their C400 or C450? In the coming month I will be looking at tunes and then exhaust options...

B) ALSO*, this is directed to OE tuning, if you could please provide AFRs and Knock Sums of the tune after a few pulls (this will for sure calm the masses) on an excel sheet for example ....supposing there are 0 knock counts across the pull and AFRs are at a good level this will be my tune of choice no doubt

93 octane, and on my C450, I'm assuming slightly better gains which would make this thing run with a stock C63 : )

Any chance this tune will be available on the handheld so you can flash it back and forth? I would be very interested if it becomes an option. If I can't flash it back to stock before service I have no interest in the tune.

OBD2 flashing is not available. No planned release for the future. ECU send in only.

C450 AMG
Thank you for your replies as always.

When analyzing the dyno, it appears the stock turbos run out of steam on the top end?

Is that fair to assume, and also, what size do you believe the turbos are, furthermore, what would you say is the flow rate?


Thanks

2015 mercedes c400
Those numbers seem kind of low that means stock u lose over 100 hp from crank to wheels that's a lot. I'd would think stock would be like 285hp 290hp to wheels

Dyno dynamics is known as one of the "heart breaker" dynos.

Dont quote me, but from my experience the numbers are usually 15-17% lower than dyno jets.
