boosting problem ?

[m0sch]

hello

i dont know what my car has been mapped to but since iv had it its been boost to about 13 psi holding round about 9 psi

over the last few days its ben all over the pllace sometimes boosting then holding ten psui and other times it just boosts to and holds 5 psi

if i boost to 5 psi and let off and go straight back on the power it boosts back up to ten and holds ten

i thought nothing of it but now its doing it alot very often and i dont know what it could be i know i need a remap but dont know what could cause it to suddenly start doing this ??

any ideas ??

thanks
