as in, do you tee them off the same lines? why are electrical ones better?

 

It would be easier to run wires through the firewall then a vaccum line. I think accuracy is going to be pretty much the same as long as you have a good gauge.

i did run my mechanical boost gauge through my firewall.

 

Mechanical and Electrical are basically almost the same. Except Electrical might be a little more accurate, not by much though!

Also, with Electrical, most of them have cool features like red flashing lights hwen you over boost, peak boost memory , etc...

I have a mechanical boost gauge and its like 98% accurate.
