M4 dynos at 424whp and 425wtq :O
basically, imagine your pedal being unable to go all the way to the floor.
the secret is how they tap into the DME, which is not something that would ever be revealed in a log
would be cool if they had a "try it before you buy it" promo. put down a deposit, and if you don't like it, just pay return shipping.
but i don't think they manufacture the handhelds themselves, so they might not be able to unlock them again as easily.
I also have the RPM limit raised 500rpm on mine and it pulls insanely hard top end..you won't regret getting a tune, infact i know you'll be laughing after you WOT it and be asking why it doesn't come like this stock

Then the next part would be to find a comparison between one of the OTS map vendors and the dyno tune. Curious what the delta would be like.
I really need to read more into this platform before i bore you guys with questions that have been answered over and over

Definitely. Nothing mind blowing, but another 10-15 or so whp wouldn't be totally unrealistic. Hard to give a definite number though.<br />
<br />
Could also fine tune drivability to how the customer likes it. <br />
<br />
I mean realistically, I hope these off the shelf tunes aren't riding on the DME's safety fallbacks to achieve higher numbers (then again like I said earlier, I think all they do is just increase the throttle angle on these cars). Without any logging, who knows what's really going on behind the curtains.<br />

Not every car is the same, so they're more than likely leaving room on the table for safety, based on the lowest common denominator. With a custom tune, you'd be able to find your car's individual limits.

LOL! Sounds like my lawn mower
How about this... if you send in the ecu for tuning and don't like the tune, send it back and we will revert to stock and refund you (minus shipping)

I think this should help... I don't know of anyone else offering this type of protection for you..

Section
C63's curb weight = 3,963lb or 1798kg
The weight difference is not that huge, only 378lb or 171kg
Power to weight ratio with the official horsepower:
M4 = 425/1.626 = 261hp/ton
C63 = 507/1.798 = 282hp/ton
I say it's not hugely impressive, but the M4 does seem to be underrated more than the 507.

The op said the car has 485 hp / 490 lb ft
Even 400 lbs is worth 50 hp
That is a lot
Not impresseed

That said, there have been LCI C63s that weighed in at 3,820 lbs (one was a member here) and there have been F80s that weighed 3,590 lbs.
The weight difference will vary depending on fuel load, options list, etc.

3585 for the auto trans, 3530 for manual. If anything, driving a 335i with another 100 horsepower stock is pretty impressive. It might not sound good but it can get the job done.

That is the eu weight and includes 75 kg plus 90% fuel
BMW USA does not detail it
They do in the UK, Germany and the rest of they world
BMW UK
Weight
Unladen (EU) (kg)
1572 [1612]
EU/Germany:
1. Leergewicht EU ( Car with 90% fuel, 68kg driver, 7kg luggage (75kg). Latest EU definition uses only driver @ 75kg )
so 90% fuel and 75 kg load
1612 -75 = 1537 or 3381 pounds
EU Kerb Weight/Leergewicht EG:
Latest EU definition of "mass in running order" (curb weight) according to 1230/2012/EEC:
"the mass of the vehicle, with its fuel tank(s) filled to at least 90 % of its or their capacity/ies, including the mass of the driver, of the fuel and liquids, fitted with the standard equipment in accordance with the manufacturer’s specifications and, when they are fitted, the mass of the bodywork, the cabin, the coupling and the spare wheel(s) as well as the tools"
Previous EU definition of mass of the vehicle:
Weight of car with fluids at 100% and fuel at 90%. Driver included in type approval and official documentation. However the defintion of "Mass of the vehicle" does not include driver, but the EU-Directive defines that the weight of the driver (75kg) shall be included in type approval applications. The weight is given for the base vehicle with no options mandatory for the kerb weight.
(these do not include the 75 kg for typing)
The EU type approval number for the M3/M4 is: e1*2007/46*0377*06 and e1*2007/46*0377*07
These are the minimum weights listed in the type approval specs:
M3 DCT - 1560kg
M3 6MT - 1520kg
M4 DCT - 1537kg
M4 6MT - 1497kg
1537 ~ 3380 lbs

M4 13.7
507 13.4
Hmmmm
400-600 lbs lighter
Better balance
Wider tires
Dct w/launch control
7 year newer technology
And yet the AMG is faster or at least equal
Let's hope AMG improves the w205 more than bmw did the m4
