STOCK 2023 M340 XDrive Jb4 Map 2 Dyno Results
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.

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.

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

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* .... |

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
