Autometer from piers
I think that piers is probably the cheapest with the exchange right now (US-Canadian). I have Autometer Pro Comp Ultra-lites and am very pleased with them. I installed them myself, it was really easy. The only special tool is a 1/8 pipe thread tap and if you have a small tap and die set it is usually included. Make sure you put Pyro probe before turbo, there is a specific area it should be placed in manifold. I don't have fuel pressure but I'm sure it is simple also. Piers has autometers in silver or black, I have 3 silver guages in a pillar mount. Looks sharp, work excellent.
