And never shim your wastegate
Autometer gauge is popular... There are other reputable and more reliable gauges out there, also.
Also, when it comes to aftermarket gauges, you have a choice of mech or electric. This is also a personal preference. I'm more partial to mech gauges, myself since all of our idiot gauges are electric, why be redundant?
Cons on mech gague is harder (time consuming) to install and electric gague is literally a snap.
First gauge should be a water temp as it is extremely crucial to have your rotary at the proper temperature and DO NOT install them by the neck of the water pump as it will not give an accurate reading. it is best at engine casing. Then, go to oil pressure gauge. And as your mod number increases, it is a good idea to ck your tranny temp as well.
So, Boost gauge, water temp, oil pressure then go into other gauges at later stage.
