How simple is it to increase the horsepower of my stock 2017 C 43 to match the numbers of the 2019 C43

jb1 or racechip

Mr. J

It's easy to boost your stock 2017 '43 to power levels slightly higher than the 2019 with any of the mild piggybacks out there. The Dinan sport is the cheapest, it'll get you to about 400 crank hp. The JB1 is only a little bit more expensive and it'll get you quite a bit more hp than a stock 2019 is rated for. The Racechip is the most expensive and slots higher than the Dinan but less than the JB1. Most of these piggybacks are very simple installations that are basically plug and play.

Anyone try the Performmaster Tunning kit?

Nah, You're better off getting a JB1 or JB4 tune, You'll get wayyy more power than 2019 C43

I agree i have vr tuned box and the HP increase is very noticeable

AMG C43 3LV6

Does tuning damage the car long term?

Why doesnt MB just produce a C43 with the same HP as that with a tune?

Thanks.

I'd imagine yes, but nobody know how bad and how fast as the platform is still new.

​​​​​​​It is the same as 16-18

He's asking about the '19 which has a small HP bump

I doubt boosting the turbos 1.5psi each- (which is what you get from JB1 on map 2) would damage the turbos anymore than usual. Since turbos started becoming popular in the mid to late 80's, performance enthusiasts have been boosting them 5-8 psi or more over stock- BMW even had a feature a few years back called "overboost" which allowed the turbo to provide boost over max stock numbers for a brief period.

In theory I am sure the engineers compensated by allowing quite a bit more than the 6 psi max each turbo see's stock and remember full boost is only under wide open throttle- which most only do briefly, unless your tracking it.

Any of those piggybacks invalidate your warranty?

Excuse the ignorance, but what changes were made to the engine for the 19 c43? My thinking was MB just leaned out the AFRs on the c450/c43 (16-18) and thus increased the power.

Update: Just checked and saw the 19 gets a bigger turbo charger? That's great, anyone know what the flow rate is? What is the flow rate of the c450/c43 (16-18)?

I don't know anything about tuning mb, I come from the subaru world

What do you mean by casual connection?

osidepunker

ok, I understand the concept. It's the same thing on the subaru side. But the big difference is normally you flash the ecu and subaru knows you ran a different tune. The fact that you ran a different tune is what the manufacturer uses to say you changed something that caused the motor to blow and they'll deny warranty

Can mb tell if you used a piggyback?

RichardCranium3

Your question is too generalized, but more or less, yes, all of them will. If you have a tune and anything mechanical fails that would normally be covered under warranty, once MB (or any manufacturer) finds out you've tuned/modified their systems, they're going to claim the failure is in some way a result of the modification to the system, and not cover the repair.

Now that does not mean that if you have a suspension component fail or or your window motor dies, or whatever else, that it won't be covered, as those parts don't necessarily have any relation to the tune. It's just not as black and white as saying "tune = warranty voided."

Last note for the new people in this thread....if you enjoy being confused and reading muddled legalese, CFG is your best friend. Otherwise, don't feed the troll. (you'll see why when he responds to this)

RichardCranium3

100%, unequivocally yes

osidepunker

This is all I needed to know. I'm not into tuning an expensive brand new car and voiding the warranty if I pop the motor. But I've never heard of piggybacks before. I was thinking that if you remove it and MB couldn't tell you had one installed then it might be worth considering.

I laugh every time I see someone cite MM as a defense for a warranty claim denial. All the dealer has to do is refuse to do the work, and then what will you do? Spend $50k in legal fees fighting them. And given MB has a legal team bigger than OJ's your chances if winning are slim to none. I would say none if you used any type or tune or piggyback and the issue is engine or driveline related in any way. Although you will get laughed at for throwing $50k into the wind.

I'd like for someone to show me just one case of a consumer suing an auto manf. under MM and winning. Just one.

RichardCranium3

Hardly similar circumstances to applying an aftermarket tune that intentionally changes the operating parameters of the car. Apply that same case with today's technology in place and I have no doubt BMW would be able to prove the engine was over-revved which caused the failure, and therefore be right in not covering the repair under warranty. No judge or jury in the world is going to give two ****s about our first-world tuning problems, assuming any owner was silly enough to take it to court in the first place! Go sleep with your polar bears...

Clint Westwood

You can cite cases where it's obvious the modification had nothing to do with the issue, but if there's any gray area good luck. Here's an article posted just a month ago and guess what happened to Ford owners?

https://www.autoblog.com/2010/12/28/...-car-warranty/

"In such cases where the vehicle was under warranty, claims were denied and engine warranties were voided; the carmaker simply confirmed that head gasket failure was indeed due to installation of the power chips. The carmaker was (again) well within its right to deny claims and void engine warranties."

RichardCranium3

I learn and trust everything I know from the internet. Am I doing it wrong?

Clint Westwood

You can write dissertations as long as as often as you like, but put any kind of tune on your car, try to make a warranty claim related to the engine or driveline and see what happens.

Clint Westwood

I haven't missed anything and not once argued against these 2 points. In fact, I vehemently agree with them. However, they are the polar opposite of what you argued before. Just how stubborn are you? Even the attorney in link you posted disagrees with you. He makes it very clear that if you tune your vehicle and expect warranty service on the engine or driveline to be paid by the manf you will lose. Very very clear!! Did you even watch your own video? He also clearly states that even if you're right the costs may outweigh the benefits and you'll be left holding the bag so in many cases it may not even make sense to sue.

Go ahead and tune your vehicle and when you request warranty service for a fouled fuel injector I will be laughing.

osidepunker

HAHAHA I forgot why I dislike forums. Thanks for reminding me fellas

I agree with Clint though. If I put a tune on, pop a motor, and get denied warranty claim, I would come out the pocket, swap the motor and move on with my life. I doubt I would win and it wouldn't be worth trying.

But if I thought there was no way MB could detect the tune I might consider it...

But really though, the car is fast as is and its got a smooth power band. Not jerky and messed up like the STi. I'll just drive as is.

I only asked because I was curious, everyone knows the MM act is useless in most cases
