I think the car is stock with 28k being I just got it.. first dyno pull 565hp/553tq

2 pull i video with the airbox scoops removed 566hp/574tq all tho with scoops removed, hood closed and going down the street cant see that helping.

but a 20lbft of tq gain.

This engine is sooooo underrated from the factory.

565 is about what you get with a tune, this car has a tune

Bryan Y

My car did 599whp I don't think it was tuned

xsboost

I will be getting a tune and catless downpipes, then dyno it again.

I thought most tuned cars make over 600hp and over 650tq? but we will find out in a few weeks.

AHI

Your car is tuned. That cannot be factory whp
But your wtq is low for a tuned car....

silvers2k

That's a pretty good number considering I dyno'd @579whp on a dynojet tuned.

Just curious, what tune and downpipes are you getting? Any plans on hitting the drag strip?

I am considering speedriven.

I have had it to the track once,12.1@119 best as it sits, still learning how to drive it. as i am used to the Buick with no tracktinon control, race mode ect..

Impressive time with the Buick!

Did you turn off the traction control off on the benz? What launch technique did you use?

And best of luck with the tuner of your choice.

your car is tuned most likely, unless someone messed with the dyno setup.... and most M157 tuned cars are making under 600whp... only a few that are over 600 and most of them have downpipes

kponti

With that trap speed I will say you have a very optimistic dyno. Typical P30 cars dyno in the high 400s at the wheel

gaspam

^ didnt see the trap post before, but after looking back seems trap speeds are stock looking and dyno numbers are tuned looking... trap speeds dont lie, dynos can be manipulated to lie

silvers2k

Amen to the trap speed comment!

99lightning

well if you want to make a $1000 bucks come up here and show me how to manipulate my dynojet 224, I will make sure that nut job from sloppymechanics is there to straighten the person out about that dyno.

gaspam

you can mess with the dynojets weather station so the correction factors skew the numbers upwards...also the dyno readout in the video above is in STD correction factor, that will skew the numbers upward too. you can also run the car in gear that is further from 1:1 final drive the transmission will have a larger mechanical advantage over the dyno. In turn the numbers will read higher and give false numbers.


wonder what making the weather station think its 125F day does to correction factor

xsboost

WOW Tuff crowd!!!
I just bought the car 2 weeks ago. had it to the track the day after i got it.

this week the weather was 68* prefect for dynoing I also put 3 gals of 104 octane mix with the 93 pump gas **** fuel, so it would not pull any timing
if any knock was detected. it has the stock paper air filters also. I just got some K&Ns for it. lets see what happens after the a tune and DPs

kponti

20 + rear-wheel horsepower to be gained with just race fuel so let's be optimistic and say 30 rear wheel horsepower gain. 530 to the wheels is still about 30 to 50 too high for a typical P30 package but a lot more believable.

xsboost

I am not sure who would get their car tuned, and leave stock air filters

PeterUbers

People that want to fly under the dealership radar and receive warranty work ... Just a thought

kponti

I did, so did the TXE55, we eventually went with UPD filters but for a while we used stock

xsboost

Different air filters would void a warranty?

Little brother here 2012 E550 4MATIC - AMS Tune , Catless DP and AMG Exhaust

520whp and 600 wtq

xsboost

Removed my ECM today and sent it to Tony Lawshee for a tune. also order a set of catless down pipes From Speedriven, and installed a pair of K&Ns

it looks unmodified to me, I dont see any drill holes.

It will be put back on the dyno, and back to the track when mods are completed.

screw991le

I agree, wondering by how much. On both NA and Turbos.
