Hello all,

My turn now.

I just blew my motor out last month, probaly a week part or bad injector connection, it's not clear yet. I had overboosted @24psi, i don't think tune was an issue. But, anyway, i replaced motor with an 80K miles "brand new" N54.

I would need a conservative tune to make sure i would not blew motor again. I am a bi afraid. Motor has been installed 2 weeks ago, i will change my oil next week, and after, i'll be ready to do some pulls.

I would like Trebila have a look on it, if it's possible.

My car and my mods are:
335XI 2008 N54
Pure Stage 2 DD turbos,
2" inlets,
CTS Intercooler, DCI,
CTS ChargeP with Forge Diverter Valves with yellow spring,
Magnaflow exausts and you know what,
RB PCV Valve, 3.5Bar T-Map sensor,
Recent JB4 + MHD backed-end flash Pump.
I'am running on 91 octane

My goal is just a save tune, not too agressive that will not be hard on the life of the motor while beeing a cool daily drive.

Thank you.

It is most likely your JB4 that is protecting your engine and tricking the map4 mode.

If you look on the JB¤ interface, you will be able to see what tricked the fault. Do you have the JB4 app?
