Default Newbie/Just installed Full JB4 S55 on 2015 M3 - 09-13-2020, 11:15 AM

Hello,
New to forum and to the JB4 kit and looking for some guidance /advice.
My car is a 2015 M3 Manual Sedan. I have installed the JB4 S55 Kit from Burger. Larger Intercooler, cold air intake, colder plugs and oil catch can. Also have installed the JB4 box in stage III mode with mobile access.
Pump gas 93 octane. Can I get the advertised 600hp on 93 with this kit?
Thanks in advance for any help

Mark

Crickets :-)
How do I know if the JB4 is limiting boost in certain gears?

You can't make 600whp on 93 octane. Going to need E85 and our BEF added in for that.

If you need tuning advice though post a JB4 log on map2 and lets evaluate it.

Boost by gear reduction is set on the user adjustment page and also visible in logs.

Thanks Terry,
Would be nice if it advertised the fuel requirement on the S55 webpage :-)
No worries though, loving the kit at the moment !! If I install the WMI kit on 93 pump what would be my approx HP?

PS, where do I find the user adjustment page?

Thanks

Mark

WMI lets you more or less max out the turbos so like E85 it's just a matter of how aggressively you want to run it. I'd suggest the dual BM7 nozzles.

In the app under settings, advanced, user adjustment options.

Thanks Terry,
I'm guising with the S55 kit installed and 93 pump I'm probably around 500hp. Car runs very nice. Would like a bit more, finish the tune around 600hp.
