Hi, i have a sti 3 with apexi power fc mapped at 1.3 bar boost but seems to be over boosting alot lately to 1.45 bar at times were it hits a fuel cut,
Ive changed the exhaust since so would that be the problem??????
I tryed turning the boost down on the apexi comander but seems to still over boost what ever i set it to????
Any help or advice would be great please,

Plus the idle seems a bit bouncy sometimes as if it may stall????
Think i need to book a remap asap.
