Hey I need help and I need an opinion.

I bought a Greddy Boost Guage that is read in kg/cm2 or bars, but I hate converting all that. But on the other hand I would like to buy a prosport boost gauge but Im worried about the quality.

Out of the two which one would you pick? Greddy boost gauge measured in bars or a mechanical prosport?

 

get a Prosport electrical. I had one, its awesome and smooth
