i recently had my car remapped but i`m pretty sure the actuator has gone weak .i have an hks actuator in my shed with a slight bit a modification this would fit to my 18g can anybody see a problem arising if i do this providing i turn the boost down to match what it was mapped at...cheers for any input...

 

morning all.

 

Should be ok but on the safe side i would contact somewhere like powerstation to ask their advice
