Default NEED HELP, no really do

right people i bought a wrx about a year ago, last owner had put a blitz Dual Boost Controller on it the solenoid has gone bad so have decided to ditch it and put it back to stock.
I spent today putting it back to standard with new vacuum hoses, the problem i have is when i put my foot down it will hit 15psi on my gauge. I wont lift ill keep my foot down and it will drop down to 10psi then will boost back to 15psi then drop down to 10psi and back up again and so on it wont hold boost.
I never had the old resrictor pill and my mate had one spare the only trouble is hes now told me its a 1.0mm prodrive one and not the standard 1.2mm could this be causing the problem or my it be something else.

Looking back at the OP's last thread it's a 51 plate Bug WRX... Which solenoid are you running? the standard OEM 2 port?

It's spiking because of the small pill size , either drill your old one out to 1.2 or a 1.2 mig welding tip will do the job
