I hope this thread can serve as the OFFICIAL flash tuning dyno comparator...

Who has the best tune?

If you have dynoed your c63 before and after, please feel free to post your results here (with any additional mods)

I feel this thread will go nowhere... my only advice is please do a search on each tuning company & choose the best for u.

Boring.

Why do you feel that way?

There is no good data on any thread to enable potential buyers to compare tunes.

Tired

If you search you will see that comparing tuners only escalade to a "tuner war" as "I'm better than the other".

Honestly, don't worry about hp gain on the dyno, no one will ever tell the difference on the road or even on the track.

My dad can beat up your dad...

+1.
Different cars, different dynos, different conditions....etc etc etc.

Do you have any issue with m3 vs c63 threads?
PSS vs other tires?
Vorsteiner diffuser vs Euroteck/Revozport/JL Motoring?

This is a discussion forum and I am sure there are others like me who wonder if all tunes are roughly the same or if there are significant differences between the different tunes?

I highly doubt I am the only one who is curious and would like to hear objective results that don't come from a company's website.

Sorry if I offended u with my post & advice. I didn't mean to.

Carry on with ur post & good luck in ur search of the "best" tune.

It always turns into a cluster F.

Pretty much all tunes are within 5-10hp of each other.

Better idea would be to take 1 car to the track and run it with various tunes.

If you're going to compare dyno results you need to have same car, same day, same dynamometer.

I would think only then you can truly compare results.

Otherwise you can have different results based on car, elevation, temperature, etc. and your car may not produce the same results.

why the hell do you wanna tune your car anyway? you have P31 stick with it

I am confused with this - would like a tune but don't know what to go for. There's so many out there. Basically trying to hit 4.1-4.3 secs to 100kmh

lol seriously you guys are obsessed

I would guess that any tune you get from OE, EC or Velos would get you there.

Try looking beyond that to see the value of a tuner and what is included, handheld device or having to send it in,# of tunes included, # of free tunes, cost of each additional tune, customer service, etc. and make your decision based on who you feel most comfortable with.

Search the forum for feedback from others and you will see dyno results, track times, etc.

Thanks bud. I have a few options but unclear:

$1300 with a handheld and 4 tunes from Eurocharged including shipping
$1370 with a local tune and dyno including BMC air filters but no handheld - this will give me the e63 stats 512hp and 644Nm
$1400 from Velos with a handheld and a tune
$1600 with a tune at a local place with nothing else
$1800 with a tune at a local place with a 1 year free service

Not sure which to opt for?

Very well said!! People are happy with their tunes mostly due to the overall experience they have with the tuner (price, variety of products offered/included, customer service before/after sales to the final driving experience of course).

As others have said, hp gains are subjective due to different factors. So basing ur purchase on the highest hp might lead to disapointment.

My advice would be to go with a reputable tuner on these boards.

I personally have the Eurocharged handheld device and have been happy with the way I have been treated. I was equally impressed with the power it gave my car.

I have also heard good things about OE and even that their tune might be faster than some of the others. They offer a handheld too.

Velos is newer to these boards with their tune offer, but has shown some good gains as well and offers a handheld like the others. They have been monsters in BMW tuning lately too.

Your local tune which would give you E63 stats doesn't sound like a good deal. Someone correct me if I am wrong, but don't the other tunes put out more than 512 hp?

Velos is claiming 50 hp and 45 tq increase on p31
Eurocharged is claiming about half of that
Not sure what OE is claiming

So the differences btwn Velos and Euro claims is substantial and worth investigating IMO

I believe the chart you are referring to was actually a C63 with a tune and an x-pipe, modified exhaust and filters. That would explain the higher numbers.

My only issue with velos is that their numbers never add up and they had the following to say on the other benz forum:

"Sorry for any confusion which we may have caused.

To answer a few questions, the stock run is from a standard C63 not a P31. A P31 model will dyno higher stock but will achieve the same peak figures as a standard model once tuned.

The chart used in the original post was used in error. That chart is from a C63 equipped with our tune and an x-pipe, modified exhaust and filters."

I don't recall them ever actually explaining it in this forum even though I have asked them to clarify numerous times. I don't know of anyone putting out 100 rwhp with just a tune only. I suspect they're about the same and maybe slightly more, but IMO an additional 50 rwhp is hard to believe from just a tune.

This had been gone over so many times. Dyno numbers are meaningless unless they are all done on the same day in the same location and the conditions dont change.





and OE tune is the best.

Maybe bro but from 451 or 457 to 512 is quite a big difference and I'd be very happy with that. It's the cheapest option for me.

Eurocharged would be your cheapest option if you're looking at it that way.

You get the 4 tunes included plus any updates for free.

You also get the handheld device.

Plus, you don't have to open your ECU.

They're also proven with many happy people having posted back to these boards.

You won't know what you have unless you dyno with the local shop. That could be an extra charge to you as well.

I'm just sayin.

I will go with O.E after I install headers/full exhaust..jus looking to get in the 475-490whp range
