Cannot speak to the vendor you mention, but I know for a fact with DME Tuning you will feel the difference in many ways!

besides EC tune what have you done to modify your performance?

I currently have Sport Cup 2's on my GT S so I'm hoping they'll also hook up.

Tune and Downpipes! They make all the difference!

They are pretty loud. No downpipes yet but it'll help. I don't do long trips with it so it doesn't bother me as much and I'm used to it by now. SC2s need a lot of heat to hook. I know the PSS that are stock are pretty awful, even when warm. Curious on how PS4s are.

Nothing. Tune and tires.

Besides the dyno and seat of the pants, have any of you actually gotten actual numbers after the tunes? When I say "numbers", I mean verified 60-130, trap speeds (1/4 mile as well as half mile).
Dyno numbers are great and all but what kind of trap speed improvements are to be expected?
I know my AMG GT S is not a dragster but since we're talking about a mod that increases power, traps and times are indicative.
Renntech has shown 10.94 @ 128 MPH (via their YouTube).
Weistec did 10.96 @ 126 MPH.
But what's disturbing is a stock one went 11.2 @ 127 MPH which shows the tunes above hardly made any improvements towards this.
I know there are a zillion variables between this small sample size of data, hence why more data from actual owners would be helpful.

The turbos on these cars are tiny and run out of air around 5500RPM. I'm guessing AMG had to go with tiny turbos to keep a reasonable powerband since the 4.0L displacement is lower than previous AMG models.

Quick question guys, do any of you guys run the Renntech 200 cell sport catalytic converters on your GTS in Texas? If so have you been able to pass state inspection with a stock tune and the upgraded pipes? I am looking to get a tune and downpipes but being able to pass the Texas smog check is a big selling point for me... Thank you in advance!!!

R760 by Renntech dyno run:
This is WKW - stock vs R760
Turbo's swap
Downpipe
BOV
BMC High-Flow Air Filters
ECU
Getting car tomorrow as they are still installing aero pack, but did a test run today, felt completely different car.
