Hi Guys, my first time here. Not sure where i should post this.................

Recently purchased a 2005 Legacy B4 JDM. Been having issues making boost.

Everytime i reset the ECU the car makes a little over 1 bar of boost and then i here a ping and it go's into Limp mode which will not pass 1/2 a bar of boost. While driving you feel that the care wants to make more power but its being restricted. Anyone encountered a similar issue?

Swapped the MAF sensor, MAP sensor checked the CAT for airflow restriction but nothing works except resetting the ECU. Then as soon as i make full boost. The car pings and "LIMP MODE" again and it will not pass 1/2 a bar of boost.

Any help will be greatly appreciated.
