So another dyno thread :P
*Update post #29 with another dyno session after installing headers*
Wanted some baseline numbers and comparision between the stock tune, eurocharged V6 and V7. Gives a baseline before I install headers and the flex fuel kit.
Car- 2014 507 ed
Mods - row boxes, afe filters, 2nd cat and resonator delete w/straight pipe
We did 2 pulls with each tune(Stock, V6 and V7). I started with the stock tune for 2 pulls, then loaded the v6 tune and had two pulls, and finally v7 for two pulls. All runs were done in 5th gear and over the course of one hour.
Conditions - 90 degrees F, 52% humidity, altitude 4500
Results (Uncorrected)
Stock 1 - 423whp 400wtq
Stock 2 - 428whp 400wtq
v6 run 1 - 430whp 401wtq
v6 run 2 - 430whp 401 wtq
v7 run 1 - 421whp 410 wtq
v7 run 2 - 437whp 413 wtq
Results (Standard Correction)
Stock 1 - 435whp 411wtq
Stock 2 - 441whp 412wtq
v6 run 1 - 442whp 413wtq
v6 run 2 - 443whp 414 wtq
v7 run 1 - 433whp 422 wtq
v7 run 2 - 451whp 426 wtq
All runs went to 6800 on tach except v7 run 2 which went to 7500. Graph didnt exactly correspond with the tach but it doesnt matter.
So we appartenly have a strong stock motor but not a huge difference between tunes. Obviouslly the increases in hp and tq are evident but minor. With that said, if you look at both of the runs for the v7 tune, from 4500 to 6000 the a/f is certainly richer then v6 and even stock. Theres definitly room for improvement there.
**Response from Jerry at EC - "tunes NEED at least 5 minutes of driving to start the adaptation process again.
We have to cruise at 30mph for 5-10 minutes some days to get the car making power. With a little more adaptation time V7 would have made 10whp more"**
Since I was strapped to the dyno and paid for an hour, I wasnt going to do a drive cycle on the dyno let alone the street.
At the end of the day its just numbers. Ultimately have 2 goals.
1)500+ whp 450+ wtq
2)high 11's with a 121-123 trap
More to follow....

long tubes since they're larger tubing will decrease lower end torque but add power up top. since power is linear and added gradually you don't necessarily "feel" the difference.

Nice post OP and well documented.
No need for the unicorn pun, all my stuff was documented correctly and my numbers were proven with all the conditions as well as a few others on here. EC keeps pushing forward

Think of the bright side: bigger pull, more peak horsepower, less $$ spent on burning rubber when pulling away from stop lights

somthing must be wrong with your car or your butt dyno needs recalibration. The power increase after catless headers for me was amazing. I feel like I noticed it more then when I went tune only. How do you not feel 40 plus more to the wheels that's substantial. Op thanks for the post. Interesting how there was only a slight change for any of the tunes over stock. There very well could be an adaptation phase like they said.

When I did a tune on my car, we didn't remove it off the dyno. But with each pull, the car kept making more power.
Eventually it started leveling out, and my tuner told me it won't make much more power than that.

I can certainly say that I feel no difference between stock and either v6 or v7. I can see people with a p30 car saying the tune is night and day. That I can believe. But coming from a 507 edition, I dont feel anything.

I'm not one of the guys who this is my first amg as its my 3rd even less first time modding one of them, headers was legit night and day. Maybe you need a EC tune

If you're adding headers to your car, you should have a significant power increase. If you are not feeling any power increases, you should definitely check for exhaust leaks on your install. That might be the root cause of your power loss.

You lost a **** load of low end from 2k to 3500 where the car wakes up.
I'm running bigger headers than you with 2 in primaries that kill my low end even more than yours.
Im trapping 118 tune only and gave an honest review of my headers.if I could go back I would just delete second cats and call it a day at 450whp.

The FI Headers that you recently installed also utilize the same Tri-Y design as MBH Headers, which IIRC, are known to lose a bit of Torque down low. This may also contribute to the loss of Torque you saw above

but I really think this could be solved with the tune. Leaning out the a/f in this area would help (assuming its not running lean already)

My EC V5 was running rich, as you'd expect for an off the shelf tune. Jerry worked on a few versions and leaned mine out, and I have great power throughout the rpm range. AFR is around 13.2-13.3 at WOT at the top of 3rd. Running MBH headers.

I thought you had cats thought,can you clarify your exact mods on the car

Guys running V7 - is it just me, or does this tune drink A LOT of fuel? I mean like a lot... Compared to my stock car, when I was really pushing it and driving like crazy I got around 23l/100km (10 MPG) and now yesterday I got 30l/100km (7 MPG). Even when I'm not pushing it that much I can see my car averages about 3-5l (1 gallon) more fuel.

Yes P31. I have a lot of mods, some are relevant here and most are not. 44O kit and 180deg thermo may make a difference, who knows. Do all the Ultra underbody braces make a difference with how the car hooks? Don't know that either. Same for CF driveshaft but that wasn't on for my best runs. The basics for my best runs are:
MBH headers w/ 200 cell cats and X-pipe, straight pipe back to OE mufflers
EC V5 "race" tune w/ Sunoco 250GT gas
Carbonio air boxes (reflective heat taped) w/ aFe filters
Cold air intake
Weistec colder plugs gapped at .040
275 MPSS tires at 24psi
H&R springs

No dyno. I have a wideband AFR gauge setup (Innovate).

Do you have the factory rear h-pipe or just straight to mufflers?
