how to tell if turbo is on its way out
ok so ive had an issue with my car and as of yet ive not had time to get to a tuner because of work and the Christmas holiday shut down .but did have a friend ask a tuner while his evo is having the engine rebuild.
so if the pipe is pulled off the turbo and actuator the turbo should boost at max output right .
my question is if this is done does the ecu now have no way of stopping the boost .i.e if it was in limp mode would it still hit max boost
i started a new thread as its kind of a new question and want to know these things for future reference sorry if its been asked millions of times but cant find much with search .theres bits and bobs but not the question im asking

thanks jay .so if the turbo make only 0.65 wether the vac pipes are on or off its to do with the turbo .ive done the straight pjpe from turbo nipple to actuator and got bang on 0.5.i also popped the c clip off the actuator arm and hooked it over the back of the wastegate flap arm and it still felt/made same bar.the actuator feels fine tbh .not stiff or too loose .wanted to test weather it was opening before full boost .so its safe to say turbo is dead no smoke or strange noise or even play in the inlet and spins freely by hand .is this common .is it just tired

the pill is in there .ive even tried a mig tip 0.8mm (vf24) .thats why i asked if the ecu could cause boost to drop even without any vac pipes to actuator .it doesnt get any higher like the turbo wont pull any further .as if it was maxed out .ive reset the ecu with romraider .( still not logged a run out yet as im still trying to learn to know whats what .and whats best to log .when i reset the ecu it said reset successful and the said turn key off then on .but no change what so ever .surely if ecu pulled timing id get a small amount of 1.2 bar ( mapped to ) before it went back to limp mode assuming some knock was detected .thats why im looking at turbo as fault .is there any other things before i go to a specialistits not my everyday car so i dont need to use it .but id rather save myself money if i dont have to pay someone hunt
