Dropped my car off Black Market Racing in Phoenix today for Custom tuning. Did a quick baseline run today before I took off. Car made 543 hp 605 tq stock. Will update once its dialed in. With dyno sheets.

Best of luck!!

what mods?

Tell those b*tches at BMR I said hello!

Amg63-

Damn those are really strong numbers for a stock car. This explains why you trap 11.5@123mph on a stock e63s lol

Geno51

lol ok will do Mike get your meth kit and come over and get tuned lol. It's nice to have a local shop that can take care of us. Regardless of the issues you had 😉

Geno51

Base line was with RADO DP and the intake spacers and filters on stock ecu so to not be miss leading not fully stock just stock tune. We are in phx AZ and today it was 75* and the dyno was at 1500 feet altitude

So the final numbers will be on the custom tune only I told them to just keep it safe on 91 octane ****ty Arizona gas but I'm hoping for 590 hp and 700+ tq honestly is I can run consistent low 11s at 127 plus I will be more then happy. With our gas crappy 91 octane and our DA air I do not expect to set records. But the dyno sheets I'm sure people would like to see when done

Geno51

Very true although my car is not really a factory freak. It's been very close to being one. No doubt in my mind at ATCO on new stock tires in good air bone stock it could of run a 11.49 at 124 or better.

Impressive for stock!

I'm guessing your numbers and 1/4 mile time would be better at sea level ?

Geno51

Should be yes

Just curious, what made you go with custom vs off the shelf tune? Has your shop done a ton of m157s?

Geno51

To answer the second question first. No they as a shop have not done a ton of M157s. But the tuner whos doing it used to work for a company that has tuned some of the fastest m157s out there. Add to that his group of people that he talks with exc. Hell yesterday he was on the phone while sitting in my car with a guy from Germany who tunes only AMGs over seas. He was bouncing a few questions off him. Then add that he has tuned no less then 5 1300 + Hp cars. So I am more then confident they will get me dialed in.


The reason I have chosen to go the custom tune route is very simple. The tune is 100% made for my car on a Dyno, dialed into the air fuel ratios and knock they see while data logging. Why is this better or worse? Simple just like my cars stock numbers every car will be a little different.

When a mail order tune is made they take say a shop car dial in a tune for that car then factor in a margin of safety and ship that same tune to everyone that calls and orders it. The fact is that margin of safety can vary from car to car.

Then add in that I am good friends with the shop owner and the fact that if I need to take the car in he can flash it back stock for me with out me having to mail it in and its a win win.

I few of the cars they have hand built and tuned

This is a 1354 whp Cts V they built



Heres some custom catted DPs and exhaust they built for a GTS





GTS and a GTR in the shop getting some love




Their hand built Air water CTS V intakes. This car made over 1100whp on a low mounted twin turbo set up





If you have a shop that can tune it local I would do it every time. If I could take my car to AMS shop and they could custom tune it there I would. Same goes for Renntech or any others.

chiromikey

I'll shorten the answer for Geno. Besides the fact that custom is always better than not, the reason he's doing a custom tune is because he has access to it. The only reason most people do generic tunes is because a reputable tuner isn't easily accessible to them.

ajs76

So proximity and actual dyno time trumps historic success/volume? I'm not being a smart @ss, but actually really curious.

I have a local guy here that has done a handful of these M157's, but I'm highly concerned that he hasn't done all the extensive testing an AMS, Renn, EC etc. might have done to make sure that they are safe.

Like, with custom are you going to try and wring out that last 5% vs just building in a inefficient safety margin and calling it a day?

What's the flip side to this argument that an OOTB tuner would make? I always read about their "we maintain the mercedes safety limits bla bla bla". Is that just marketing fluff?

I'm VERY interested in your results. Thanks for posting!

chiromikey

Yes, even the main tuners will tell you that. Custom should make more power with as much safety margins, if not more, built in than a box tune. As with any tune, it's all about the knowledge and experience of the tuner.

Geno51

LOL ya what he said LOL

Geno51

Here is a video of the pull.


Im a jackass and was not thinking to video the screen lol
just shouted the numbers for the baseline pull lol

KLR CLS

love the satin nero wrap man! Going to do my CLS in that sometime this summer.

Geno51

Thank you its an amazing color

chiromikey

Any updates?

Geno51

Nope nothing yet But he told me it would be Friday.

What numbers have other stock M157 put down on that same dyno?

Geno51

Mikes E63 I think is the only other one but they did not have his in dyno mode and his is RWD so its hard to know. I dont know his before numbers but his after were something like 581-722 on EC tune again not using Dyno Mode and he is RWD. But mike stepped up to another tune since then again so his car is surely stronger now

gaspam

i have these same turbos on my weedwacker

Geno51

LOL BorgWarner EFR

They are amazing turbos so im sure your Weed Wacker could take down the Redwood National Forest
