I just got my boost gauge installed b/c im about to turn up the boost. I went for a drive and the Greddy Electrical gauge reads:
.5-.6 bar in 1st
.5-.6 bar in 2nd
Spike to .7 then back to .6 bar in 3rd.

My question is: Why am I making too much boost. Im at stock boost with no boost controller or anything.
