Hello guys,

I am looking for a base tune for my E46 328Ci, if anyone has anything that I could use, since it is a complicated scenario, please let me know.

Engine mods done:
Sport exhaust headers, M54B30 Intake(with DISA), M54B30 Intake camshaft, M54B30 Throttle body and MAF, I am trying to run it on MS43, stock file for M54B30 has quite a rich mixture (smells like unburnt fuel), currently running a M54B25 file but the car loses a lot of power after 4000RPM, so I drive it slowly.

I am thinking of tuning it professionally, but until then, it would be appreciated to have a more normal tune.

Thanks in advance.
