I am wondering whats the difference between Mechanical and Electronical Boost Gauge? Which is better and why? Is it worth to spend extra money getting Electronical Gauge?

anyone?

This has been covered too many times...
Mechanical: Fluid (air) goes into the cabin, directly to the gauge, via tubing
Electrical: Fluid (air) goes to a sender via a shorter length of tubing, which then transmits the values to the gauge via wires, sometimes through a control unit first.

Electrical will have extra features like peak hold, playback, etc. When it comes to a boost gauge, one or the other won't give a a noticeable difference in performance, accuracy, or safety. Of course, with the extra tubing for a mechanical gauge, there's an increased chance of kinking the tubing or having something rub through it and cause a leak, which will give you incorrect readings. For things like an oil pressure/temperture or fuel pressure gauge, you're going to want to go with electrical... Oil and/or fuel coming into the cabin isn't a great idea unless you're totally sure the connections won't fail and start spewing fuel and oil all over you.
