ECU Tuning Group | Mercedes Benz CLS63 AMG Twin Turbo ECU Upgrade
Gains on a CLS63 AMG TT w/ Performance Package on cold engine using 91 octane are 70hp & 95-105lbs tq to the wheels. Using 93 (European 98 octane equivalency) octane, gains are approximately 90hp & 115-125lbs tq to the wheels. Administering 93 compared to 91 octane is a night and day difference.
Please remember, gains posted was on a very hot engine. Dyno testing took place here in Los Angeles driving from Downtown LA to South Central in traffic in boiling hot weather.
Please inquire about other Mercedes Benz models. Details will be presented about any vehicle upon request.

What Id like to know is how is the tune administered? Via OBDII? or is the ECU pulled, taken apart and modified?

My apologies. Vic55 was kind enough to answer the question. The dyno sheet posted is based on 91 octane in extreme heat after driving for 3-4 hours. Other tuners out there usually measure gains at the vehicle's optimal level, while the engine is cool. As I stated earlier, administering 93 compared to 91 is a night and day difference.

in your first post you said 100hp gain over non performance & 90hp gains over performance !!
1) did you tune a performance CLS/CL/S 63 Bi-turbo ?
2) will the 63 performance have more power after tuning it than the non performance ?

Gains posted were 80-100hp. Both vehicles, performance or not, will peak at the minimal 553.40hp 632.72 lbs tq assuming you're using 91 octane. Remember, those gains are on a hot engine.

You are correct, the PP car gets more boost (18.3) from the factory which is easily changed on the non PP car.

what is writing by who opened the thread is that non PP will gain 100hp and PP will gain 90hp !!
so is the diffrence 10 hp between PP and non PP ?
read the advertisement carefully.
" Reprogramming the Mercedes Benz CLS63 AMG Twin Turbo, we were able to achieve an astonishing 80-100+hp 150+lbs tq to the wheels over stock. More power can be achieved by replacing the cats with high flow race cats.
Gains on a CLS63 AMG TT w/ Performance Package on cold engine using 91 octane are 70hp & 95-105lbs tq to the wheels. Using 93 (European 98 octane equivalency) octane, gains are approximately 90hp & 115-125lbs tq to the wheels. Administering 93 compared to 91 octane is a night and day difference. "
not trying to bash or anything, why claaiming 70hp for 63TT with PP while they didn't tune one until now.

Non PP using 91 octane (same as Euro 95) we achieved on a hot engine 80hp 150lbs tq. If you have the PP minus the difference on the extra hp from the PP. Whether you have PP or non PP the car will still max out at the same.
For example (and this is an example).
Stock 518hp Tuned 618hp
PP 5**hp Tuned 618hp
