I tried the search but was unable to find this topic. I am install a TRD s/c soon and was looking for opinions on what type of gauge to use. I want to mount it on the steering column, but did not know the benefits of mecahnical or electrical. Thanks.

 

mechanical uses a long piece of tube to connect to the vac source with a t-fitting.

the electric uses a relay that you connect to your vac source. Both are pretty accurate if you run them correctly

 

As long as you have a digital screen for the boost gauge your good.

 

What scott said. Either one you have to hook up a couple electrical wires just with the electrical gauge you have to hook up a couple more.

Just dont get too cheap of a gauge. On cheap mechanical gauges some of them will "jump" when you hit a bump in the road. Also I have compared digital readout gauges against what ecus are reading and the digital is always off. So I wouldnt recommend a digital unless you want to spend a bunch of money on the AEM.

I think it's worth the $$$ going w/ the AEM Tru-boost gauge/controller, as it's just that, a gauge and a controller... It allows you to program two different settings to it that are controllable from the gauge... there are two buttons on the face of the gauge for the settings...

 

^ S/C won't need the tru-boost gauge/controller.

Just get the regular AEM boost gauge, the 35lb one.
