I know and EGT is a must and so is A/F Ration guage and the kit already comes with boost guage. Main question is what one are suppose to use? Electrical or mechanical guage and which is the difference? Is a Fuel Pressure Guage necessary? Someone be kind enough to show me a link or point me in the right directions as to which guage to get and what kind? Thank you. Boost is a coming.

It doesn't really matter what gauge you get as long as it's effective like a LED AF guage VS Digital Numeric AF gauge. Of course the Digi gauge will be more accurate and easier to tune your car.

Say you have an electronic boost gauge you can program it to do stuff at certain times like over boost light or something. Pretty much any boost gauge will do.

Bottom line is just get what worx and don't get something you'll be sorry with later haha like me and my 0-30psi boost gauge that only goes as far as 4 when I boost.

Wanna trade? I have a 30-0-20 Ultra lite boost gauge. Problem is it doesn't go high enough. :7 I need a 30-0-30. Tough problem to have, no?

I asked these questions a while back...

Go to the autometer website for the explanation between electrical and mechanical. Mechanical guages require the substance you are measuring to run TO the guage... so if you have a mechanical oil pressure guage in the car, there would be an actual oil line that runs into the car to the guage. I'm going with all electrical guages... they convert the pressure/temp/etc. to an electrical signal and send it to the guage via a wire. A little safer and the guages will be easier to mount.

As for the rest of the guages:
- Exact Air/Fuel (corbin is supposed to make a nice one)
- EGT or Pyrometer: There has been recent discussion and it is believed that these are the exact same guage.
- Boost Guage

There are a lot of optional guages... I think that I'm going to get:
- Water Temp - The factory guage sucks ass!
- Fuel Pressure - Nice to know when using a pressure riser.
- Oil Pressure - The lifeblood of the car...

Other people have:
- Oil Temp
- Tranny Temp - mainly for automatic cars

Hope this helps
