I've just purchased a boost and pyro gauges from Geno's. They are the Autometer 2 1/16 inch black-on-black with white letters and a red pointer.

I plan to install them on truck no. 2 in my signature.

I am looking for all the pointers I can get. Anyone?

 

drill the back hole on the manifold not the front you will get a better reading the rear cylinders get hotter than the front. the boost is easy just route hoses and wires good so they wont chafe.
