Ordered ISSPRO guages, EGT, Boost, Fuel Pressure, from Diesel Manor. Good folks would recommend to everyone.

My questions are:
I bought 0-60 boost guage, do I really need a 60 psi guage or should I replace with a 40 PSI guage. (I like to watch the arm go up and down) THe 60 guage doesn't move that much unless I hammer down. Will I peg the 40?

Next question. And not wanting to re-vist the "how to drill the manifold" questions, but where to drill the manifold. Trying to decide if I should drill on the down section of cylinders 4-6 or on top at cylinders 1-3 (both are suggestions per the instructions).

 

You want the 60. I have a Quad Std and can hit 40 before it settles to 38. The needle moves enough with the 60, it should entertain you.

I put my Pyro between 1 & 3. I would suggest searching, as you know there are other options.

 

I installed mine in the down section as depicted in the instructions. Not sure if there is much of a difference, some put it up because they say they get a better read for overall cylinder especially the back two.

 

Back two? #5 and #6? That would be hard to drill.
