I was wondering if the tial 40mm would be a better choice over the HKS 40mm unit. How about flow does one flow better than the other.

thanks

i don't know about the tial but i was inspecting my car the other night and found a boost leak. i traced it to the w/g (hks standard) and initially thought it was a torn diaphram. after testing i discovered that it was not the actual diaphram that was leaking but rather the the valve guide opening. air was escaping from between the actual valve and this opening. i thought it was kinda strange but apparently others have had this problem as well. if i were you i would go with the tial just because it is easier/cheaper/faster to service over the hks and the quality is on the same level as the hks unit also.
