I’ve gotten 7.1 once on my C2S pdk, starting from about a 45mph roll. Stg2, catless + PSE on 93 octane during cooler outside temps last year.

I think I can crack 6.9 by getting my technique down better, and probably high 6’s if I go with e85.

Same engine, no?

Yes the S and GTS share the same engine and trans with the 30 hp difference being ECU tune. For example, with the M engineering tune in my S it added 100 hp to the wheel (450 at the tire) and 470 ft lbs of tq to the tire shredding any GTS. Now if you tune the GTS you can regain the advantage

because the GTS engine has no mechanical differences from the S, the M Engineering tune should deliver the same peak hp and torque numbers for each car.

M ENGINEERING is freaking amazing. I purchased an M-Engineering tune for my 2020 Carrera AND 2022 Carrera S, when I tell you this made the car fun, words that you're reading on this screen can't describe it!

Communication: 5/5
Every email that I sent to them was responded to almost instantly (YMMV) and very professional. Since I am a novice to this kind of stuff, they made sure to explain everything to me in terms I could digest.

Shipping: 5/5
Their custom OBD reader is solid and very sturdy, and packaged perfectly.

Tune Turnaround: 5/5
My first tune took a day, I lost my 2020 Carrera after a few months, and the dealer upgraded me to a 2022 Carrera S, and that tune came in 1 hour!

Summary 5/5:
M-Engineering has a very, very specific sale policy. Please read it. Despite my issues with my old car and how long I've had it, they worked something out with me that was very, very fair. I can't complain.

If you're looking for a tune from a company that cares about your warranty, has no need to send your ECU in, and responds to messages and issues very fast, this is the company to use.

2020 Carerra - Stage 2 Tune - Successful, no engine explosion.
2022 Carerra S - Stage 1 - Successful, no engine explosion. Requesting Stage 2 after Akrapovic exhaust.

Yes - No returns. No refunds. No exception.

reddsektor

for stage2, you need sport cats or catless pipes

zachr

You can't go stage 2 with just an Akra slip on. You need high-flow (sport) cats, or go catless. The slip on makes a sound difference, but the airflow limitations in the stock system are in the cats rather than the exhaust/muffler.

edit: lol beat me by 2 mins@reddsektor

Too funny....setting the bar high with "no engine explosion". Have to agree M-E does a helluva transformation well within the limits of safety.

Anyone have #s for C2S stage 2 with only sport cats on 91 crap gas?

RoughRider911

What numbers? 0-60, quarter mile, dyno. No one is taking their 992 to a dyno that I’ve seen - unless they dyno tune it. I have a 992 C2S with catless pipes on 93 and there’s a large difference in acceleration, throttle response, and enjoyment with the tune. E85 is just another level up. Couldn’t be happier with the tune or M-Engineering. Charles always touches base and asks how I’m liking the new updates and the car runs great.

^ The best way to optimize the tune is to get Soul's nonvalved exhaust set up, which consists of sport cats(or catless) and an exhaust that are effectively 2 cannons that go from the headers to the tailpipes (and if you are really a man of steel, get aftermarket headers).

With that plus 93 octane tune, you're basically a missile (for a Carrera). Smile as you fly by other cars, and they hear that flat 6 roaring down the pike.

RoughRider911

Have any dyno graphs to back that up? Based on conversations with M-Engineering (correct me if I’m wrong Charles) there isn’t much of a benefit on headers on stock turbo CS’s - the stock units flow quite well. The main bottleneck is the cats.

M Engineering

Thanks for the kind words everyone!

From our testing with aux EMAP sensors on a variety of exhaust systems, the best power and lowest EMAP readings (EMAP is exhaust manifold pressure, you don't want this number high!) come from running stock headers, and a turboback exhaust system that is a true 3" full system with no valves and a proper x-pipe in the center. Yes, you can still make good power if you want valves, but if you are trying to pinch every ounce of horsepower you need to ditch the valves and run that pig with no bottlenecks. We have made the biggest power running @Soul Performance systems on this chassis.

shrimp money

Are you saying that even if we have you program the valves to be 100% open all the time, it still won’t flow as well as a non-valved system?
