I'm using one on my srt and tuning it is easy ...
THAT'S FROM THE MANUFACTURE
The body is crafted from anodized Type-6061 aluminum. The hose barb fittings and locknut are constructed from electroless nickle-plated brass.
The Signature Series unit even incorporates a stainless steel spring and your choice of either a chrome or ceramic ball bearing. This combination allows your engine to realize gains of up to 30 psi while being able to fine tune your desired boost setting with ease.
The hose barbs included with your controller utilize a captured o-ring that creates a perfect seal while fully encasing and protecting it. It will never crack, break, or rupture.
We wanted our newest offering to last a lifetime, and it will. This entire unit is built to withstand the harshest of elements. We even back it up with our lifetime warranty..
