I really like Mercedes but it’s not a great tuner platform, period. It’s much easier to get big power and number out of Audi or BMW. I was in for service at my local Audi dealership about 6 months ago and they had a used 2018 Audi TTRS for sale. To kill some time I took it for a test drive and was really impressed so I bought it. It’s now tuned for E85 and has all the bolt ons plus an upgraded turbo from Iroz. It’s ungodly fast and cost me less than half of what it would cost to get the same numbers out of an AMG.

i respect the technology but Tesla bores me to tears.

MB is a horrible tuning platform and why after 3 AMGs I finally bailed. I think I might do an Iroz 850 TTRS myself. Hypercar+ performance at a budget price is hard to pass up. And my sentiments exactly on the Tesla!

What do you have now?

RS7. Took it to the track last night for the first time in 3000ft DA and the silly thing with its “off the shelf tune” ran a 10.43 on old 21” Continentals without even launching hard. It will easily run 10.2s with good tires, decent weather, and me learning how to launch properly.

That’s bonkers. What’d you trap?

What’s it pushing to the wheels? Is it just tuned or did you do downpipes/intake/exhaust?

chiromikey

Besides the tune, just DPs and intake sourced from an independent vendor. It trapped 132. Didn’t even bother with a dyno since it’s just an “off the shelf” tune and random parts.

Those RS7’s are the real deal!

What is so damn good about them? Is it the tranny? I feel like the AMG has the better AWD system and comparable/if not better power output?

chiromikey

This is for a different thread but yes the trans is a big part of it for me.

So is the F90 m5 just as fast with launching as those RS7s?

Even with the same mods, and same tranny it doesnt seem the F90 is quite as fast as the RS7 from a dig.

chiromikey

Time will tell but I’d bet the F90 will launch just as well as people learn how to drive it.

Amg63-

Already so many are trying, it just doesnt launch as hard as RS7 it seems. I think the BMW has more finnicky TCU, and im also not sure its durable enough to handle huge torque in first gear either,

MuffinFlavored

which car pulls hardest 60-130mph? it seems like:

1. F90 M5
2. RS7
3. E63 S

Amg63-

60-130 is another story. I thought for that it would of been for sure

1. F90 m5

2. W213 e63s

3. Audi RS7

you sure RS7 on roll is outrunning the e63s with equal mods?

I spoke with GAD motorsports.

€27k ($30k) (with labor), but you have to pay to ship your car to them.

Air filters
Tune
GAD turbos
High pressure fuel pump
Blow off valve (lol)
Stage 1 transmission upgrade good for up to 1150Nm

Amg63-

They are by far the best AMG tuners out there, they pretty much are the only ones who i see can make AMG amonst the fastest modded cars out there.

The thing is, i certainly aint paying no $30k, plus shipping it out to germany and back to get it done. Also, if something goes wrong how would you deal with them to fix any issues?
