STOCK 2023 M340 XDrive Jb4 Map 2 Dyno Results

Daily2023M340X · 06-02-2023, 11:53 AM

Hello group. I got my Stock 23’ M340 Xdrive on the Dyno (Mustang Dyno) today at R/T Tuning. They are installing an AA Catted DP, CTS Charge Pipes, MST intake and some other bits for me today. I asked that they Dyno the car before and after install. The car is running map 2 with the JB4 on 94 Octane. Hopefully this helps everyone wondering what Map 2 does on a new stock m340.

This is stock? Around 400 hp?

Stock map or stock parts running map 2 and then mods and map 2?

They’re saying the only modification it has right now in those dyno runs is the map 2. So just a jb4. Not a stock car. They will then install the additional mods OP listed above and re dyno the car.

Derekrpd · 06-02-2023, 07:22 PM

Did you get any baseline runs and numbers without the JB4?

I did not

Throatpunch · 06-02-2023, 08:27 PM

Nice- i live 10 mins from RT. I’d like to see the car!

JITH · 06-02-2023, 08:34 PM

Excuse me for the confusing..... if I am correct JB4 means the car is modified in its stock hp, correct? And, map 1 means what here?

I apologize for the confusion. So the car had no bolt ons or other modifications besides the JB4

JITH · 06-02-2023, 11:19 PM

No need! Just I am here the one that is not getting it clear, my fault. Does the JB4 added any hp or not? Just curious.

Thanks in advance.

Is there before and after dyno graph? I'm curious what the relative change is, not the absolute result.

Yes the jb4 is a modification. It is a piggyback tune. OPs numbers are with the only modification to the car being the piggyback tune jb4

JITH · 06-03-2023, 11:07 AM

Thank you very much. I ask this because some videos and info around the B8TU in 340's and 440's are state that it has around 400hp without any modifications.

So basically stock power levels haha, looks like the JB4 works right at the beginning of the RPM range and then the DME immediately squashes the extra boost

Also, you're there, WHY wouldn't you do a run without the JB4 *facepalm* ....

No because it doesn’t stock have 400 hp at the wheels.

NLJ · 06-04-2023, 08:31 AM

Should have run Map 0 and then Map 2 to see the difference!

I dropped the car off to see the difference between JB4 with and without mods. Going back later this month to see if there is any difference. Unfortunately there wasn't enough time to run after mods. But we will see

Cjvillarreal101 · 04-23-2024, 01:19 PM

Daily2023M340X did you have to do anything specific to get it to run on the dyno? Not sure if the LCI G20s require a specific mode to properly run on the dyno.

G30M · 04-23-2024, 08:30 PM

err sorry but where's the before and after?

WernerM340IX · 04-24-2024, 05:17 AM

That doesn't seem like much gain to me.
I have an M340IX
2023 Europe OPF fully stock.
390.1 HP // 569.3 NM
