Boost levels for MHD stage 1 n55e

[timchump]

Hi

I have a e82 n55

Running a mhd stage 1, 93/94 octane (99ron uk)
only supporting mod is a mmr charge pipe.
I’m surprised how much boost it’s running.
Consistently just over 1 bar
I think I’m right in saying this mean bhp is over 350, but mhd quotes 330bhp for stage 1……..
Is it safe / Do I need supporting mods, like an intercooler to run this much boost?
Again mhd app says stage 1 is no supporting mods…..

I’m hoping that map is looking at all the parameters then deciding it’s ok run more boost, however I’ve got no ideas how mapping cars works

See attached, using bimmerlink, 4th gear pull

1st column time seconds
2nd column boost bar
3rd column boost set point bar
4th column rpm

1 bar is just over 14 psi so sounds about right i would upgrade the intercooler tbh

n54 stage 2+ runs almost 19psi
