so

I've got a brand new garrett 31 actualor
new bailey DV30 dump (recirculating) and cold mount
T3 is brand new
I've got a stage 2

I take the boost pressure not from the turbo (as original) but on the hose between throttle and intercooler (cold side)


my problem :

I accelerate
arround 3000 3500, pressure is 0,8 and after, pressure will grow 0,1bars each 1000 rpm and finish arround 1,2-1,3 bars
I use the amal valve

if I disconnect amal valve, result is the same (just less boost)


in my mind, when I accelerate, I show have the "max boost" value and after, the car increase rpm and boost will be lower :
pic boost arround 1,3-1,4 and after arround 1,1-1,2
I do not have that

where should I check please
