I have had STRI EGT, Oil Temp, Oil Pressure and Boost Gauges installed for a while but they never seem to have been working properly. The shop that installed them used a Greddy adapater plate for the Oil Temp and Pressures sensors. I have already had to replace the oil temp sensor once because the original never worked. When the car starts up the gauges will move to the same position each time and will not move or will barely move while I drive even if its an hour long drive. EGT sits at about 8, Oil Temp sits at about 180 and Oil Pressure sits at about 22. Originally they moved a lot more but now they barely do.

Is this a case of STRI being suck gauges, a bad installation or is there something else I can look at? Thanks for the help.
