ok i have an 88 civic with a dohc zc and a t25 turbo
i want to run 7 psi . my safc says im boosting .53 kg cm/2 (i think that is 7.5 psi????)
but my boost gauge that i just put in said 14psi!! witch is way to much for my engine. witch one should i belive the boost gauge is "T"ed into the fuel pressure regulator vac. line is that a bad spot?
my wastgate is a stock eclipse wastgate what psi. is it set at?

you would know the difference between 7psi and 14psi hehe

change the graph on your vafc to read in bar. 14.7psi is 1 bar, so 7psi would be roughly .5 bar.

If you have your boost gauge T'd into any vacuum line, it is probably right.

what fuel management do you have? an AFC hack will most likely not be able to scale the map sensor voltage back enough to not create a MAP sensor check engine code. If you're boosting 14psi on an AFC hack, your check engine light would come on and the car would bog

if you were running 14psi on a stock d`6 sohc you would be driving right now, your motor would be gone..
you shouldn't boost more then 8psi..
