I`ve read that the Jdm twinscroll actuator is known to be quite weak at increased boost levels, and Martyn Jeffery told me that the vf 53 actuator on my spec c needs to be stronger. Reading around the subject, I`ve seen some opinions against holding boost to higher levels, re mechanical longetivity.
I have an HKS uprated actuator ready to go on, so what are the pros and cons, and is it an intercooler- off job? Thanks.
