    • Renntech first to break the M157 600 wheel horsepower mark with their C218 CLS63 AMG, new M157 horsepower record

      Congratulations to Renntech who simply keeps raising the bar on the M157 platform seemingly week after week. Renntech hit 602 wheel horsepower with STD correction on 93 octane pump gas. Yes, incredible. The CLS63 has a revised tune, intercooler upgrade, and a downpipe modification with 200 CEL cats. This provides 119 wheel horsepower over stock and 188 pound-feet of torque over stock. The best part? M157 tuning is just getting warmed up.

        You haven't seen nothing yet.... I wish I could disclose the prototype numbers from the next round of upgrades.

        RENNtech is definitely loving the turbos.... Click here to enlarge

        I bet! If the torque didn't drop off so hard up top it'd be pushing some AWESOME horsepower numbers for 93 octane, not that it isn't strong already.

        I saw a new cls63 with a tune last night get walked by a "stock" z06, maybe I should tell him to get this tune with these mods!

        Speaking of Renntech, how are they doing with their 335D tune?

        Yes amigos I have the RENNtech mod and its unbelievable, a lot of people dont believe I only have an ECU mod until they hear me screaching from a standstill Click here to enlarge, the only problem I have confronted is to have the check engine light come on and off from time to time and disappear, I went to my mechanic Buru Auto Service here in the Island. we saw the error codes one for the MASS Flow Sensor and the other code was I believe the OS sensor from the rear next DEf tank, I have yet to go to the dealer since the car is currently working great with and w/o the check engine light. I will go thru warranty but have to wait for my connection at the dealer that will let me go thru Click here to enlarge. I will keep all of you posted okClick here to enlarge

        Joseph. You posted a false Article. Renntech are not the first to break the 600RWHP number. Teamspeed UAE tuned a CLS63 and they made above 600RWHP in a lower reading dyno, that is Dynodynamics. If you know about dynos. You would know that it reads lower than a dynojet.

        You serious man? A dyno dynamics you say? Never heard of one of those. Was the dyno in something called shootout mode? Or did it show the correction? Because a dyno dynamics usually reads lower but can be set to read much higher as well.

        Additionally, this would be the first 600+ dyno in the USA and is on a dynojet so that is what I am going to go with. As far as I am concerned since I can not verify that other dyno or what was done or by whom, Renntech has the record and was the first to do it in context of every other major tuner on a dynojet.

        The stuff going on in the Middle East I always view with skepticism, like the company who claimed to have turbo upgrades for the X5 M and X6 M and then disappeared.

        qouted from Teamspeed UAE:"ECU tuning, and Installation of Turbo Down pipe. the car made an additional of 160 hp,at mid range, and almost 90 hp at peak. Torque of 190nm extra.

        You should do that with Renntech.

        I dont really know which company you are talking about here. Teamspeed UAE is a Legitimate performance shop. It is run by Nasser Al-Shamsi. Temaspeed UAE is a verfied dealer fo Kleeman, Vaeth, Xtra, Supersprint, Techtec, Caragraphic and many others. Check the websites. When you dont have knowledge or any info I suggest you stop spreading BS around and get your facts straight bro.

        Says shoot_8?

        Additionally, what is the red baseline? If that is without software why is it so high on a dyno dynamics that you are claiming is set to read low?

        Uh, I think you are reading way too much into some inflated random dyno figures from somebody no one has ever heard of.

        I'm going by reputable tuner results in the USA and last I checked Renntech's dyno's correlate with their 1/4 mile figures which also happen to be the fastest.

        Tell these guys to get to a strip.

        Why? Because they are backing up everything they do and currently are in the drivers seat on this platform?

        Ya, sure it is man. You are putting some random UAE shop on the level of Renntech? You know, the company that has the world's fastest Benz and the highest horsepower as well as quickest 1/4 mile figures for the CLS63 AMG and the M157?

        Cool that someone posted some inflated dyno and you like that. I stand by my post, Renntech, and when Teamspeed UAE has a slip to back up their figures give me a call.

        Your Dyno Dynamics graph screenshot clearly says "Flywheel Power (HP)" on the left-most X axis. This is the Dyno Dynamics readout that takes a wheel horsepower figure, and inflates it to try and calculate a crank horsepower guesstimate.

        If you don't know what this T-UAE car made at the wheels, which is what this thread's about, you can't say it's more powerful than the RT car.
