hatch sti boost creep
 

Hi guys I'm in need of some advice on this easter Sunday please lol I've got a hatch which WAS running 345/410 on standard turbo with no issues what so ever the car never missed a beat but as you do you want more power so I recently fitted sc46 with 1000cc injectors and perrin 3 port bcs (parts were 2nd hand but working fine when removed) all parts were fitted correctly by a subaru specialist aswel now on for the mapping, the guy who was mapping it had mapped it previously BUT were having major issues with boost creep (over 2bar) I've just been out and ran it with just wastegate pressure and it's still doing it?floor it in 3rd at 2k rpm and boosts to around 1.4bar but as soon as I get to 4k rpm the boost just climbs and climbs now it's going back to the guys to have another look next week but I was wondering if anyone on here has any advice or has experienced anything similar themselves,I just wanna drive my b****y car :wonder::wonder:
