Totally agree if the car has been built by a reputable company, you have all the paperwork, receipts etc. Then surly its an ideal car to buy.
You have a purpose built car that's ready for the street / track etc.

Unfortunately for the OP it seems he bought it with 3rd party tune on all ready which looks like the issue.

A friend tried a 3rd party tune on his Weistec Stage 2 E63 (From a very reputable company) which gave him a little more BHP but within a month he started getting CEL's and it was just not running right. He put the original Weistec file back on and no more issues.

Not exactly. As with all used things bought, you have to be wary of things that can potentially be wrong with it. The seller can be a straight up person, but he/she may not know there was a potential problem already. Sometimes you get lucky, sometimes you don't.

The point I was trying to make is the problem/fault doesn't lie with Weistec or any other tuner, but the fault of the previous owner and what he/she did to the car after it tuned and modified correctly to begin with. Like average joe states, the problem seems to be the "modified Weistec tune."

Don't get me wrong; I bought my C63 used as well. She started at 9,000 miles...3 years later, 80,000 miles and still running strong. I've driven from Sacramento to LA and back multiple times and she's never let me down. I'm actually taking her to LA again this weekend for a quick road trip to visit old friends.

Two reasons, 1, we know you did it right. Weistec built this car and the previous owner supposedly had no issues with the car while Weistec was taking care of it with their file. 2, you run a Weistec file (I assume).

Your car is in good hands and you understand the con's to leaning it out for more power.

Weistec is a stand up company for sure they have gone above and beyond for me previously when they didn't have to but they did

Where is the op now
IHis been pretty quiet

I think the chances of a safer conservative tune causing a problem is fairly low, but yes changing anything from stock CAN cause an issue.

I agree with last 15+ posts. You can't expect to mod a car and to be perfect. I think we all can agree, it never is! At the end of the day, a very powerful machine was built and it was a time bomb waiting to go off. Hope somehow issue get resolved.

OP gooone!!! lol

PeterUbers

Can't fight logic and common sense

Duc1098E500

Once again you can't buy common sense.

Worth the wait

I think the point has been made, Weistec has been exonerated and the OP has disappeared.

Let's let this one die....

Jasonoff

Weistec ruined my car. It uses way more fuel/tires now and they won't take responsibility...

djrabbi

LOL! I would first blame MB USA for making "powerful" machines. They didn't give us any warnings that we will get 10MPG and go through tires every year!

Petakii63

That's thread is very laughable. First off the smart thing to have done, is not open up a thread bad mouthing a company. Secondly, If the car is having this many problems, the whole car should of been shipped to Weistec, so they can look at it. Now let's get this straight... You want Weistec to fix your car, when you had a third party file on it? I'm having a hunch that he had Eurocharged try and retune the car... Now the transmission is shot because the car has probably been abused and has seen the course of many standing burnouts and launches... The thing that really makes me scratch my head is the op clearly said he has a Ferrari, but can't fix this car?! Aren't you embarrassed? None of this adds up...

Also where is the op? Haven't heard from him in awhile?

PeterUbers

My car is stock and weistec is refusing to warranty it....wtf weistec!!!

djrabbi

Makes sense. Weistec's tune is like $1500+ vs. Eurocharged is $100. This is why Eurocharged didn't want to tune FSP pulleys until they realized people are buying them.

rentzington

EC posted, they never tuned the car.

djrabbi

Since when you believe everything you read on the internet? EC probably didn't tune it but why would they have the car from Mid 2014? Maybe OP didn't have the money to fix it or it was an EC tune kept under wraps? Always three sides to the story.

rentzington

and you obviously have an axe to grind

djrabbi

And I am hella bored at work LOL!

HEY.....THIS IS MY OLD RIDE !

Lololol

CarHopper

Is it really?

You'll know best out of anyone here about the condition it was sold in etc.

I am Jeff

Did you tweak the Weistec tune file and put non OEM fluids into the Tranny?

sales@eurocharged.com

Please quit insinuating that we tuned the car. I already told you we didn't.

The car arrived to us with a blown motor from California at the end of July. We upgraded the motor and finished the build in October. Weistec has had the transmission for a few months and we just got it back.

Steve and I were in contact the entire time. Weistec provided all of the information we needed to complete the process.

You seem busy to me Mr. Marketing Director @ IAP Racing.

Please refrain from discussing anything related to Eurocharged that you have no knowledge about. You're spreading misinformation and as a non-paying vendor on this forum, you should know better. Please know that I'm asking nicely. There are a few people that would be more than happy to start posting about IAP Racing so we can discuss the long list of customers that have a bone to pick. The ball is in your court Ravi....I suggest you keep it civilized.

Can't wait to hear the outcome on this story

Car always worked like a champ when I had it . Never had any issues except for a squeaky belt , which Steve sent me 2 extras . I couldn't figure out how the car went from San Francisco to Houston when there are 100s of other shops in between
