Best Bang for Buck Mods?

Hi All,

Haven't been here in a while but I just picked up a 2018 C63 (base) Coupe.

Can anyone recommend a good set up for a tune, intake, downpipes, lowering? Looking for slightly better aesthetics and handling and better throttle response and obviously a bump in horsepower.

Am currently considering:
Suspension: KW Sleeves or HR Springs
Tune: JB4 or via tune via Handheld?
Downpipes: Generic good enough?
Intake: BMS good enough for just sound?


Thanks!

Congrats on your purchase!

Susp: no input, i like stock
Tune: JB4 hands down
Downpipes: only worth it if catless
Intake: BMS or ZAC black glass version

Thanks!! What makes you say JB4 hands down compared to a "traditional" tune? Re: the intake - do they increase power at all or are they mostly for sound on these car?

Thanks! Curious why you think JB4 is no good for this car?

I also think ECU tunes are better than piggyback tunes, Eurocharged has a good tune

JB4 is great for logging and controlling water meth injection(that’s all I use it for) , it is also a lot cheaper than most obd tunes.

OBD tunes change a lot more than timing and boost , they also switch on and off points for your intercooler and the speed they run at and your LP fuel pumps ramp to name a few.

Ive been through a few tunes and swear by golabworx , Kevin’s a legend , he never sleeps just tunes cars.

If your just going todo down pipes and a tune I would go with a OBD tune and get yourself a HP Tuners MVI for data logging

We have a new intake kit coming out soon. Tremendous HP gains at higher RPMs. We are wrapping up final testing at the moment and will have a forum release posting soon. We also offer catless and high flow catted downpipes with integrated heat shields cheaper than mostly everyone we have seen.

The JB4 is cheaper, equals or exceeds the performance of ECU tunes, does not leave the permanent marker in your ECU that tells the dealer your car has been flash tuned, is easily adjustable on the fly from your phone, Includes a valet mode, has boost by gear, Can control meth, And provides excellent logging capabilities that are easy to read and invaluable to monitor your vehicles true performance and health. All of those are advantages of the JB4 that an ECU tune does not offer. Plus the JB4 can easily work in unison with a flash tune.

Don't get me wrong, I have nothing against flash tunes. My last BMW had both a JB4 and a flash tune and it worked great. If I ever get to the point of heavy modifications on this car I will probably look into a flash tune to compliment the JB4 again in order to better customize more detailed parameters. However for stock turbo C63s, the JB4 just makes more sense. Again just my opinion, And no disrespect to those who choose a flash tune..

I do believe that intakes add power on our platform, however gains very. Also you will be easing stress on the turbos by making it easier for them to draw in air.

Interested in the intake too. Do you have actual pictures not just renderings of them. I know you've tested them so I'm sure you can post a few.

Am currently considering:
Suspension: KW Sleeves or HR Springs - KW always - far superior to H&R. Im running HAS kit and its perfect
Tune: JB4 or via tune via Handheld? - I did a full custom tune, but i suppose it depends how important warranty and potential power are to you. JB4 was obsolete on the f8x and f3x platforms and its obsolete on benz too. Eurocharged, renntech and weistec are all proven
Downpipes: Generic good enough? Yes and no - dont need to spend a fortune. I went with SSR and theyre fantastic for half the price of some other brands. ModalWorks would also be a great option
Intake: BMS good enough for just sound? I would go ModalWorks here as well. Thankfully this platform with actually pick up some HP and noticeable power gains with just CAI. Thats generally not true.


Thanks!

See my replies above...Hope it helps

If you only buy one modification the JB4 is it. Huge power gains without the risks and drawbacks associated with flash tuning!
