@@BrianTindall-fl5hc totally agree. You had just got your car. You were still getting dialed in to it. I think there are a lot of AMG owners watching this that are a little butt-hurt that getting a RENNtech ECU tune can deliver virtually the same acceleration performance as an AMG.
I think the real race was race 1. My camera guy even said, “C’mon man! 2 out of 3!” I was, like, “Nah. That was a perfect demonstration of RENNtech vs. AMG.” But I did 2/3 anyway.
1. The AMG isn't the p30 performance package. So it's just 518 horsepower. Weighting 4,300+ lbs without the driver. 2. The AMG is rwd so it shows it true potential from a roll. 3. The heat, humidity and altitude affects it's performance. 4. The guy driving the AMG do not know how to launch his car (he can't drive).
@@talkditingsdem5799 we did discus how he was new to an AMG beast with only RWD at the end of the video. He just needs to dial himself in to his new car is all. Correct on all other counts. The D-Alt affected both our cars equally.
Was looking forward to this. It would have been interesting for you to switch cars. This fellows reaction times killed him. The first race would be the best read for the difference between the cars. A better analysis would be for your best time in both cars. The Renntech tune certainly seems worth the money.
Yes my reaction times sucked. Not having the car for very long and a hectic work schedule didn't leave much time to get some launches under my belt. Too much boost created wheel hop, too little and it lagged bad.
If you drive the car like a rational human being, there should be no additional wear or tear on your power train. Do I get on it every now and then? Sure do. But I also don't "race" my car...with the exception of the RENNtech vs. AMG video I did. @@traybutts4425
True that. I imagine, with density altitudes closer to actual field elevation, the times would have been much closer to 12:00 sec. We might do a rematch in January, once Brian knows his AMG better. Thanks for commenting!
Would you be kind enough to send me the link about your process of finding your CLS and what to look for? Especially the engine nomenclature - M???. I am pretty much done with AMG's. Fast, but so much more expensive for service. Your CLS description and my age appear to be a good match. Thank you and am enjoying your channel. Bill in Tallahassee
Nah even with bad reaction time the Amg would still beat a 550. This video just sold me. I got beat multiple times in my gls 550 by 63’s. Now although they were sedans the gapping was disrespectful, and I regularly beat up on 53, 43, infinities, certain bmws(lol) etc i need that extra speed.

I think Race 1 was everything a well maintained CLS 63 AMG and/or a RENNtech ECU tuned 550 can do with a DA of 1550'. Some sluggish R/T's on both of our parts that race. AMG:.12.46 1/4 mile - .707 R/T = 11.75 sec. Assuming a low DA (close to sea level) and a professional class R/T (sub 0.1 sec) all the time, upper 11's could very well be expected from a CLS 63 AMG.
@@BrianTindall-fl5hc Agreed. Putting all that power down to the rear wheels only takes some getting used to. Like we agreed in the post-race, people need to get dialed in to their cars too.

Amg has additional cooling, just tunning ecu isn't suficient.

Great video.
That meter with the calculated density altitude was really great! Really like this channel as a fellow pilot and car enthusiast! Subscribed
Thabk you! So much argumentation over “Man! That car should be faster!” from people not taking DA into consideration. Blue skies!
Thanks for making this video! Some good races, if you can ever line your car up with a awd 63 that'd be sweet to see how it compares.
I had an CLS 63 sAMG all lined up, then, it got totaled. Thus the delay on producing the video. But yes, perhaps a 4-Matic AMG at some point.
Great video! The comparison nobody else has done, would be interested in seeing the 1/8 times as well.
