I’m kind of surprised XDI isn’t in that game. Although, I suppose when you’re starting with 600 WHP the crowd thins with people looking for more.
I was shocked too honestly. Plus there are two of them.

E63S Update: Spool sent out the pumps I believe last Thursday. Dyno Comp should have the pumps early this week, and I have an appointment to drop the car off on Wednesday evening. Hopefully by Friday afternoon the car is done, and we are making 725 hp+ and 850 tq+ to the tire. With 25% drivetrain loss and is 906 hp and 1062.5 tq crank.........:cheers:

Dyno Comp called and said the pumps had arrived. They requested I drop the car off ASAP. Don't have to tell me twice. Car was dropped off last night, and hopefully by the end of the week, we have our numbers. Should be good.

It begins.....
Lol it began with the tune.........

However, it did yank a Hellcat in comfort mode last Saturday. He said, "WTF". Then I really hurt his feelings when I put it in race mode.

It is fun knowing what this car is, and that it makes significantly more power to the tire and can stick it to the ground better than most other super sedans.

can't wait to find a wagon !
Do yourself a favor and get a 2020 plus they seem to have less RMS (Rear Main Seal) issue. Also join MBworld.org (if you haven't) and read as much as you can including this thread.

So...off the phone with Dyno Comp. Car is done. I won't be able to pick it up until this afternoon. They did mention that the car made the most power they have ever seen with the 4.0L Biturbo V8 without a turbo upgrade........

I mentioned I would be happy with a 725 hp + and 850 tq + numbers, and they audibly laughed. So....yeah.

So car made great power. But we are 91 octane limited. Dyno Comp's highest none turbo upgraded on 91 octane was 696. This is what mine put down.
20250116 160413

On 93/94 octane they said it would make 750+ hp.

So good numbers and I can definitely feel the tq in the low end. Looking forward to see what other new numbers this car puts down.
