E350 dyno day
Keep on mind this car has 302 hp from factory and with the parasitic draw of the auto 7spd tranny youre looking at 20% hp loss. So if you multiply the results of todays dyno you would get 333×1.2=~400hp....which seems insane. Maybe im wrong and its 302rwhp from factory.
Wish this guy was better at getting pulls on this car but he couldnt figure out the transmission i guess.
Threw this in for kicks. 1 layer sealant 2 layers p21s 100% carnauba.

The Factory rated HP of 302 is at the crank so assuming that was the pre-tune figure getting about 100HP extra is very good!
How does the car perform post-tune?
The car performs really well post tune and racked the same at wheel hp as a stock e550 which was dynod and the results posted here.
I just sealed and waxed the car so i also think that helps the appearance.

I'll be upgrading / up-sizing my wheels & tires soon.
Here's my dyno before and after (OE Tuning) on E550 Coupe:
369 HP to 430 HP
445 FT-LBS to 555 FT-LBS
At Wheel!
Definitley a good looking car whivh ould benifit from some nice wheels.
I love the concave look because it works so well with the rear quarter panels lines. Makes the car seem wider and sportier.

ill try to get more information but at this time i cant really go into too much details as i havent the slightest clue as to what he did.
But no this was not dyno tuned.

@Jeffy;' after looking at his chart i am noticing that as well. That blip towards the end shows the gain; but throughout the power band it looks like he is at 260 whp. OP you should definitely have that double checked by the tuner.
