I know who Yunick is, old school, and did as much rule manipulation as he did innovative engineering...


Ford worked as an engineer for Edison,
his best work came when he was 45 (model T)
his education was the 25 years leading up to that point
ever hear of Adrian Newey?


'improved' requires definition...was his car improved?
just because a few non-technical sorts think it is an improvement does not make it so...some power in excess of what already can't be used at the expense of efficiency, reliability, warranty, value, etc., would not be considered an 'improvement' by many


many times compromise is the best solution
a big part of engineering is deciding what compromises to make
in order for the total package to be optimized

Yes you're absolutely correct. Engine management software is key in today's engines. The software from these car manufacturers ensures that everything mechanical works as it should. Any mechanical engine upgrade especially force induction will need reliable software updates. A bad software tune can be as catastrophic as any mechanical upgrade gone bad.

Car is great stock, but there's always more you can get out of it. Obviously OP wanted to take that route since he gladly shelled out the money for it. Don't see how telling him to go back to stock and not mess with it at all is helpful advice...

If I had any knowledge at all on the matter I'd chime in, but I don't so I just hope it all works out. I'm assuming all the work was done at EC and it can all get resolved as hassle free as possible.

for all that is good and holy why man, why!!!???
the oem exhaust note is one of, if not, the best around
put everything back to stock and see how it runs...I'm guessing better


for all the junior birdman engineers who think they can out think AMG, do this:
get educated at a top notch school for 8 years for a PhD in mechanical engineering specializing in hipo combustion engines and powertrains

aquire 10-20 years of progressively responsible experience in the field

get a job with AMG and spend 5-10 years there

then leave and start a business
like the guy at RennTech
then you may have some credentials which lead to credibility


ignore ANY check light at your own peril

Something would have to be royally messed up. Has to be something more going on.

Engineer, thanks for the life lesson there bud, you're a real hero. Must be a pretty decent engineer if you're rolling in a used C63.

My current car I paid 43k cpo'ed with 15k miles, new tires, brakes and a good trade in on my 88k RS4
I think I did allright

I do not judge a mans worth on his earnings but since you apparently do I made 285k last year (150k of it banked)
Not as much as you ballers but I eek out a meager existence

You know what is really funny?
Taking a 70k car and rendering unusable
A perfect 2013 C63 that has to be trailered and that the dealer may refuse to work on
Ha ha
Real funny huh??
Damn shame the op cant enjoy his machine

OP revert to stock and enjoy your car
I would not trust the people who fked it up

So i would like to thank and apologize to Jerry and Rick publicly, for going above and beyond when it wasn't their fault AT ALL, they did everything they could and hopefully things will look better for them. I never mentioned the shop's name, but people already figured it out.

Thanks for everyones help and comments.
