Weistec claims 856whp dyno with W4 turbos on 91 Octane fuel.
I am posting my own time slip from last week. Running 780whp on pump fuel. Fuel tank 2/3 full. DA ~4000. Street tires. I did only 2 runs at 20psi. I'm posting my 2nd run which was better than my first. It's nearly identical to the 787whp AMS Alpha 9 E63 1/4mile from a few years back.
Weistec, if you are reading this, I give you unlimited number of runs to beat my time slip. Surely you have run the W4 in the quarter-mile by now. If your car is putting down 850 plus to the wheel you should have 2-3mph higher trap speed. Show me what you got.
Formerly I had weistec W3. Advertised at 730 wheel horsepower. It did not make the power.
That's one of many reasons I'm publicly calling them out on their claim of 856whp for w4.
Im running GAD Motors turbo upgrade. For this run I had it set up at 780awhp. If Weistec cannot beat this run, then they have an exaggerated false horsepower claim. Silence can be very loud. If they're truthful, this thread will prove to be an awesome endorsement for Weistec.
Still only a 1.85 60 ft; is your tranny stock and stock TCU? The inability to properly launch these cars is very aggravating; you should be seeing at least 1.6x 60 ft times with how fast your car is. Mine has a mild tune and I can't get under 11.5's because the launch sucks, my best 60 ft is also 1.85

I have upgraded transmission and tuned TCU. First run I did brake torque launching at 1400 RPM with 2.x 60 foot. 2nd run launch at 2000 rpm got 1.83 60 foot.
tuning company can log data on the track, make adjustments in real time, launch using any technique they like, there are so many advantages. Knowing what I ran is an advantage. Easy challenge if their car makes 856 horsepower to the wheels. A more difficult challenge if the number is manipulated.

Have you tried launching higher? Your car is too fast to only be pulling 1.8's, I bet you can get into the low 10's with a higher launch
They make it sound very easy and indeed it took maybe half a second to set it up and go. It takes me longer because initially when I brake torque the RPM does not want to go up.
Next time I'll try launching from a higher RPM. My intake air temp was 68C/154F at launch.

Anyone that’s been around these cars for a while knows Weistec is full of sh*t and you won’t get a response.
These cars suck *** at launching but you’re either doing something wrong or these TCU tunes are BS, especially if you’re only getting 1.8s. At this point you’d be better off brake tq’ing to 2500 or using Race Start.
I don't think it's as simple as adjusting the TCU. Our all wheel drive does not put the power down effectively because of a fixed torque split between front and rear. Last year with race start i got high 1.8-1.9 60' because of wheel slip. Stock 2018 E63 got 1.7s 60'. Same day same track. Factory tires.
Weistec has been notified of this thread. If they post a better time slip maybe I will have to get a better 60 foot. For now I don't want to make it too difficult for them.

After a week or so with the TCU tune, I can say that it is not BS. Hands down, no argument. Does it take care of all the things we don't like about the MCT? No. Will it make every tuned E63 a 10 second track monster? No. Is it worth the $$$$ to have done? Depends on the individual.

I’ll need more convincing. One dragy 0-60 isn’t close to enough data. Obviously I’d prefer timeslips but any reason you didn’t at least do a 1/4 comparison with your device?

I agree one Dragy is not good data. I have not had the available time to try a few 1/4 mile runs after the TCU update. Prior best was 11.43 @ 120 with the Dragy. Living in the city, it's a bit of a drive to get to a spot to do 1/4 mile runs. I will get some done.

How about this 1.7sec 60 foot time. Launched at ~2500. Michelin 4s tires 255/35/19 front and rear.
because they dont care to go back and forth publicly with a random person (all due respect)
i never tuned my 63 because i was always concerned with issues and as its my DD i dont need issues...stock form u still cant even use all the power for daily....i dont drag so i guess tune is pointless.
but......i just drove the new one......wtf.....so damn fast and rapaptatapap all day
ams, renntech, gad, dimebag, weistec, oe, who else.....isnt their method to their madness pretty much the same?

It's because their car does not produce the claimed 1000 horsepower.
I also have a 1k hp set up for the E63. Yesterday I trapped 138 to 139mph and last year 139.5 mph. W4 cannot even beat 135mph trap because it's nowhere near 1000hp.
A 900-horsepower E63 is running faster than their "856whp" E63, that's why they will not respond.
