MAZWORKS:
Our new SR timing chain tensioner significantly improves upon the factory hydraulic timing chain tensioner which can fail when stiffer valve springs are installed. With the stock tensioner, the installation of bigger cams and stiffer valve springs can also cause excessive timing chain wear and can cause the chain to stretch prematurely. The Mazworx tensioner does not need oil pressure to operate and, when properly adjusted, can function as well or better than a factory OEM tensioner, can reduce wear and help improve reliability.
I cant see the problem when i drive with really stiff spring (dual supertech) + Solid cams from tomei + solid lifters.
NOTE: Im not saying you are wrong, im just trying to figure out why it would not work better than oem tensioner.
