FYI All Renntech tuned cars are now being flagged on MB's database. So anywhere you go, the dealer will know right away if you are tuned or not.

Maybe I'm crazy but I'm perfectly happy with a tune and some bolt ons lol. Seems like the perfect balance between reliability and performance on this platform.

Quattro is mechanical and 4matic is electronic?
what are you talking about?
the 4matic system is a fixed mechanical 33/67 torque split, and has less drivetrain losses and weighs less.
Yes it won't launch as hard from a stop, that's a transmission with torque converter adavnatage for the RS vs the AMG.
doing an ECU tune is easier on the RS, ok but it's not a big deal to have an hour of work to tune the AMG either. I don't get how that's a reason.
listen I can totally see how the RS7 is more appealing to you and not at all saying you shouldn't consider it, it's just the reasons you posted are simply not making much sense, that's all I'm getting at here.

Also, bro you live in Toronto, I live 30 mins east of Ottawa. The closest regular mechanic is 40 mins away let alone a tuner. Point being when the S/C pulley issue happened with me-it was a huge hassle, so now I feel like the most bang for my buck would be via RS7 also, it just looks so menacing. Although who knows what deal I get once I start seeing the actual numbers from the dealer. That could change compared to my math that I'm doing using websites lol.

Oh yes, you are right. I confused two threads I have here. AMG version is mechanical with fixed split. I think the new ones however would be software again because it allows 100% of power to be sent to back wheels.

i mean that's definitely not guaranteed when you tune both cars. Many here have tuned e63 for years with no issues at all. AMG are built strong for sure if that's your concern.

Look, anybody looking at a turbo upgrade realistically should not have any expectations for warranty, however anything from a tune to DP's could also void it. It's part of the risk of modding your car. You better be prepared to deal with the outcomes. I say this over and over again, the only person to blame if you tune your car and blow it up is you. You could choose to enjoy it stock, and operate in the original design parameters. Once you exceed that all bets are off.
That said, now that the price of entry into 750+ whp has reduced, more people will begin modding this platform and we will begin to get hard data on thresholds of OEM hardware. I would doubt there were more than a few dozen cars in north america running turbo upgrades prior to this year, so there really has not been enough data to know where the breaking point lies.

Now with 750whp+ the torque will also increase to well over 800wtq+ with that and be the ultimate test.

Well not necessarily. Larger turbine wheels tend to move the torque curve up the RPM range, but do not always make more peak tq. Now with stage 2s you will make more HP and tq, but the torque hit will be softer. Maybe that will save trans hard parts like baskets and shafts, but clutches are surely toast.
From a short block perspective I'm betting Pistons will be the weak link. Crown height and ring Land depth look shallow and not super boost friendly.

so in reality turbo kit is probably easier on the trans than tune only car since the tune only car is going to hit that max trq in a low rpm range like low gear launch) where trans more stressed, while the upgraded turbo car is going to lose some of that low-end trq hit and come on higher in the rpm range less abruptly

I always wondered just how much faster this car will be if boost was turned down at low revs and ramped up as the revs climbed.
Less interruption from the ecu due to torque management, hopefully that carries up in the rpm range even though more boost is coming in etc etc.
I feel like even with stock turbos using this approach could benefit. We do not need 800ftlb flywheel at 3k rpm to launch harder than we are doing now. All that does is cause torque management to mess up the fun. Drop boost and torque down to low 700 range (still over 100 more than stock) and hopefully less interruption from the ecu. I guess this is something that needs testing.
Tuned cars are not doing much better 60ft than stock.

^Jb4 was hands down my favorite tune/tuning option I have every had on any car.
Any word on if your renntech tuned E has been flagged?

it seems like a tune gains the most power like you say at lower RPM, is that still helping get higher trap which usually indicates the higher rpm power?

its not, because its not true.. you can call renntech directly, which i and another forum member did today, and renntech rep told him and me (separately) that they are not doing this.
If mercedes is flagging them then that is because they know you are tuned by other means, but not because renntech is telling them
fwiw- i am flagged and the dealership still honors my warranty (5 times since they have known i was tuned).... now if my ecu fried, they prob wouldnt warranty that though

because i did a big smokey burnout (like the one in you signature) in the dealership parking lot while yelling "RENNTECH BIATCHESSSSS... *** YEAH LOOK AT ALL THIS RENNTECH POWERRRRR!!!!" 
i kid i kid.... they know because i told them when they were working on a low fuel pressure issue that was causing misfires and they sent the ecu back to renntech as renntech had a fix for it

Nowhere I'm my post did I say your warranty will be denied because of Renntech. I said YOUR CAR WILL BE FLAGGED FOR HAVING A RENNTECH TUNE. Your warranty will still be honored. Nothing changes except now most if not all MB dealers will know you have a tune. He even showed me where on his screen the flag shows up. T
That being said, he also added it was for any car that gets the tune from a dealership. It's something new they are doing and he believes its just a way for MB to compile data. My car is NOT flagged because I got the tune back in 2015 and that was not in effect back then. Now if they have to send my ecu back to Renntech to get reflashed for whatever reason, it will get flagged then.
