Hks Wastegate Actuators

[R1Titan]

Hi fellas

I want to know if HKS wastegate actuators are reliable in holding boost steady...

if anyone from experience has used these before, do they spike when coming on boost or hold boost steady throughout the whole rev range

I understand they are set for around 1 bar.

Also, can they be re-tentioned to a set level? eg 1.3 bar????

I had mine set for about 12psi (.8bar or so) It could have gone lower again with reduced preload. I never had it spike.

I think the max they can do is about 1.1 bar without some form of controller (and you'd have to be a strong man to get the thing hooked up with that sort of preload)

How exactly is it re-tentioned/preloaded??
