Got them still sitting on my desk still because I'm slowly compiling all the associated hardware to install them. I got the boost gauge (0-50), EGT and fuel pressure (0-30) with isolator. One thing I'm a little concerned about is the Hewitt thermocouple is big, as in 1/2" NPT hole required in the manifold. The t/c tip will end up sticking into the manifold quite a ways, and it may be slow to react being so big.
Let me know if you want any more specific info.
