Hi, new to the forum.... I am looking at getting a 2012 C63 with performance pack....I have a questions for all the gurus here...

Has anyone done an ECU tune over and on top of their C63 + performance pack?

Btw, I tried searching on the header sticky post.... is there a set of performance headers that includes high flow cats?

I was just wondering the different options

1) Performance Pack C63
2) Performance Pack C63 + ECU tune
3) Performance Pack C63 + ECU tune + short performance header mated to stock exhaust & stock cats

what would the different gains be like?

many thanks.

im in the same boat..
not sure if its really worth the money for the tune with the performance pack

not to mention i dont want any warranty issues..

Jmoley

cheers.... I'll just enjoy the ride.

maybe tint out the car and upgrade the 18s to 19s + some fat tires.

I'll post pictures eventually.

To answer the questions, I can't be specific until I do the search myself(I encourage to do your on search) but going by memory I recall at least two separate test on short headers(one from Klemman and one from PLM) and they both added between 15-20whp.

Also I recall some post about people that had the C63 12' model with performance package and they still gain significant power. Again, I will have to find it but I am 200% certain about the gains.

Thanks

I'll pass.... Too much hassle to ship for you, wire money over to you from me, customs when i import it in etc....

Thanks for the offer anyways.

1 and 2 have pretty much the same power. This is assuming you're talking about the P31 performance package.

Im also very curious what the final gains would be on the p31 with the ecu tune.. Someone out there must have that answer.

thanks.

Me too!!

My buddy has a 2006 F430 (F1) and I have a 2012 Coupe PP with a tune and I consistently beat him in races in Mexico (not by much mind you), from a stop, from a roll, from 40, doesn't matter I beat him. Again, not by much. Don't know what it would be like w/o the tune though.

To me, it's worth it for the tune. I have a eurocharged tune and I'm quite happy with it. Felt the difference immediately, shifts more agressive, just made a big difference.

With LTH's on the car I suspect my winning margin would increase a bit

Still haven't had it dynoed since the tune though. Pre-tune my numbers were 433/410 bone stock with 3xx miles on the car.

Checked it out......520bhp for factory performance pack ..... (red calipers, sls internals) + aftermarket ecu tune.

On 98 ron gas..... = 93 octane gas for you guys in the USA.

What do you mean?......You got 520HP at the fly, WITH, a tune?....what did you have, BEFORE your tune, what sort of "tune", & and how did you calculate your flywheel HP?
I have P31, so I'm interested!
Cheers, Pickles.

1 and 2 will put you at around 510-520hp.

3 will put you at around 550-560 with high flow cats.

A member had his P31 performance package car tuned by Brabus and got an increase of 5hp. I personally don't think tuning a P31 car does much...

There was a thread on here where a tuned car raced a P31 car and they were dead even over and over.

Long tube headers with an X pipe is one of the best mods you can do to this car.

MHP has header with cats if you want too.

any more results on this topic i get my car on tuesday and interested on a tune asap max power!

as you can see from my info, i have a pp car and ive come to the conclusion that you only need a tune if you are going to start messing with your intake, headers, or exhaust. to my knowledge the tune gives your ecu greater parameters in order to rich-en up the fuel mixture to combat a lean situation caused by greater air flow due to modifications.

the dealership gave me alot of gruff for having a tune on my last car and as stated above, a tune over the pp+ shows marginal performance gains.

Does it include TCU or is it only a ECU upgrade?

CELLryuu

just the ecu.

you have to dig into the transmission to get at the tcu.
