I originally posted this in the Gen. Automotive section....but that is like the dungeon of the forum and no-one dares go there.. Anyway, Im buying an aftermarket boost gauge for my FC, and I just had a question. 1st of all, I plan on boosting ~12psi, 14max.(T04B hybrid) If I get a boost gauge that only reads up to 15psi, will it be more accurate than a gauge that reads to 30? I figure that the 15psi gauge would have better incremantation than one that reads to 30...and since I wont be boosting that high, I have no reason to buy the 30psi gauge. So will one be slightly more accurate then the other, or doesnt it matter?

 

if it tops out at 15psi, you won't ever know that it was actually just a boost spike that blows your engine up.
