FBO RB Turbo - strange missfire at high boost, help needed

Hi guys,
The car has new injector+new plug+new coil on cylinder 5.
Still missfires on cyl. 5 and 6 (both of them at the same tine), at high rpm, on boost over 14,5 psi. Map 2 is max. map that can be used. Higher than Map 2 gives missfire.

For all the people that experienced this and got it solved out, any help would be apreciated.

P.S.:
- new injector is coded and corectly installed, with new decoupling element and new gasket ring.
- The old plug, with 10 000 miles on it, looks perfect.
- Even tried with new NGK 5992, gaped at 0.022".
