Overboost?
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.

What does your exhaust system consist of?

Re: Overboost?
sounds like not enough boost to me.. how much were you expecting?
if it didnt rattle the pistons dont worry about it
whats the deal with bar and not psi? i like bigger numbers

alright, i just did a 4th gear pull and it held steady at .75 bar really close to .8 bar. I dont want this much boost. My fuel pump hasnt come it yet. What should i look over?

Re: Overboost?
the greddy doesn't read in Bar, i am almost positive it reads in kgf/cm2. 0.6 would be ~8.5 lbs, .7 is ~9.95 lbs. dont worry if it's just a spike, where it settles is what you should be concerned with. 1st and 2nd gear readings are worthless also, 3rd and 4th are what you want to pay attention to
