okay I have a gn1 performance 3in dp with 38mm wastegate and turbonetics 0-50psi boost controller and I cant control boost it keeps going all the way up to 25 plus sometimes over 30 and I let out instantly.im trying to get it to around 18. I have gone through and made sure I had the lines for the boost controller set up right and I still cant control the boost. it is a 57mm precision turbo. I have read maybe porting out certain holes in the dp will help but not exactly sure which ones and if there is something else I should try first before tearing everything apart and doing the porting. thanks for any help in advance.
