Not realy at that sort of boost. id be 90% sure that its just the actuater wound up to much if you say its not fouling the elbo. losen it off untill the wastegate arm is rattling then half a turn drive it if goes over 1bar if it does its something else. if doesnt over boost bring it back half turns until stays at .8 dont go over unless ur mapping it propperly

also get a new peice of pipe to run to the actuator so you nk there is no restrctors in it. and is it comeing from the turbos compressor housing to actuator or from an intercooler pipe?
