Bigger cams and map sensor readings at idle on motec?

[86psi]

Hey just curious if this is right or wrong
Anyway since I've installed my new set up with 274 cams on my motec it reads as 50kpa at idle so it won't go to the bottom of the ignition table. I've pressure tested everything and it still reads this.
Is this the norm with bigger cams?
Also my eboost is reading at 13hg

yes its normal to loose vacuum at idle with bigger cams with more overlap

Is this the old short block i had? No dramas?
