Spark plugs - BKR7E big NO

[turbokick]

Hey guys, share your opinions with what spark plugs you run your remapped 1.8t
I was running DENSO iridium IK22(on remapped 1.8t running 19-20psi with stock K03S), changed them with NGK BKR7E gapped at 0.28 and the car lost throttle response and much power esp. at high km 180-200km etc.
Going back with the Densos!

BKR7EIX for your power level.

E are for cheap skates
