2020's have the same power ratings (385 HP / 384 TQ) as the 2019s. The PFL 2018s and prior were rated at 367/384.
When you say "worth the $ over EC," JB4 is less expensive than EC. However, there is no way the JB4 will make more power. EC is a proper ECU tune whereas JB4 is a piggyback.

This is a different case on the PFL. EC tune on the PFL makes far more power, from over 20psi of boost.

Actually, not entirely correct. The JB4 makes more power than an EC tune on a 2019. May car is a perfect example. The JB4 gets me 20psi on 93 Octane, while the EC tune peaks at around 18psi between 2000 and 3000 rpm and then it’s a flat 15psi from 3800 rpm to redline. I’ve had multiple EC retunes and it will not make more boost than that.

Until you shared that info, I was under the impression that EC had caught up. I could've sworn there was someone else on this forum that got tuned from EC Canada for a 2019+ and was making PFL power, but now I can't find the post, so I may be dreaming that. Are you still running JB4?

This is all great info thanks guys!! I think JB4 boasts "up to 100hp gains" which I'm pretty skeptical of and EC seems a bit wishy washy in terms setting expectations.
i emailed with a local tuner shop and simply asked what gains I can expect from a Dyno tune and this was the response:
"biggest change on the 2020 cars is a few extra limitations they added, some essential stuff normally located on the ECu are now relocated to a module called CPC, currently not flasheable, so even with bigger turbos, we have some limitations on how much we can push until this CPC gets sorted out, for some 2019 and under we can already modify, but 2020 seems to have a new protocol, and some modules cant even be flashed. Also this modules to be flashed we need the car in person. So in simple words, its very hard to tell exactly what is the exact gains as this limitations can vary based on models and dates."
I emailed back saying, it seems like the 2020 isint quite ready for a flash tune, and the technician agreed. Looks like there are a few hurdles yet to clear before a proper flash will work / be available.

I’m really not sure how informative the video is seeing as how he takes the temperature of the outside of the pipe that he has put the foil over. It’s bound to be cooler cos of the foil, but that’s not really relevant. Also he takes the temp of the air filter. Why? What’s more relevant would be the intake air temperature or the temperature of the inside of the pipe.

Yup, I have read recently that the functions they moved to the CPC are significant. AMR/EC and others will need to devote some R&D into this before FL vehicles can be tuned to potential. There's a company in Georgia called Solo Motorsports that's doing tuning on FL2018+ models by replacing the CPC with an unlocked unit and then flashing TCU and ECU. I don't know much about them, though.

This is all still new territory. All the US tuners are singing the same song about the CPC but none have actually done it for the C43. They’ve done this for the E63S and have good results. The European tuners are all taking the lead on this and the US tuners are only just catching up. I have done the rounds with the US tuners and no one has real data on CPC mod for C43 yet. As such, I’ve taken it upon myself to work on this. I have already gotten my CPC modded and so far power delivery is much better during hard driving, the max power is still the same. There still is ceiling for the FL model that cannot be breached, but it’s not just the CPC. I was hoping it was the golden ticket, but it is not.
What's the max power we can achieve with existing available tunes?
Is EC still the best bet? AMR? JB4?

I have the JB4 installed in my 2020 C43 as well.
Did you also install their Boost Control Module (BCM)? I've been told (Terry @ Burger Tuning) in order to maximize performance on facelift models (2019 & 2020s) it must also be installed.
I have had one paid for and on order for ~3 weeks now. I am waiting somewhat patiently for it to arrive....

I have a 2017 so didn’t need one

I'm about to order the JB4 for my 2019 c43... i'm a little apprehensive about the install.
You think its easy enough with no real background in this kind of thing to do so?

Finally got my JB4 installed and DL the app!
I have had 2 tunes prior to this one, the Vrtuned box and the JB1, and the JB4 is ALOT more powerful than both.
Install was very easy after finding a video on it on youtube https://www.youtube.com/watch?v=3_rUc0jB7o4&t=222s and DL the instructions http://www.burgertuning.com/instruct...400_stage1.pdf .
Running the wire was not as hard as I thought and the app that controls the JB4 is very easy to use.
I plan on running the stock map 2 for about a week to do some logs then start messing with E85 and map 6.
If anyone has any questions or advice please don't hesitate to PM me I will help with anything I can. I have installed 3 tunes now so I feel pretty comfortable under the hood.
Next up is MST Intake!
