it is very hard to get to the last bolt on the actuator mounting plate. Most would say its a turbo off job to change the actuator's but i think R-tech managed to remove an actuator without taking the turbo off.
Im running a forge actuator with a red spring as im on a stage2 map. benefits being stronger than the standard item, so can close the wastegate off quicker and hold it shut better.
Speak with R-tech as i know nick was looking at developing a add on to the standard actuator that makes it stronger and save then need to replace with a forge item.
