Just wondering what a good strong vac reading is for an s13 sr at idle. mine is usually around 500 inmg but today i did a few things under the hood and now it seems to be a bit higher (around 700 inmg). Does that mean i fixed some sort of vaccum leak? Thanks!

On my boost gauge that reads from -30 to +30, my healthy vacuum reading is -22 I dont know what your numbers mean.

That's about what mine's reading. On my gage, vacuum is not labled as being negative, it's just kind of assumed. So mine would be around -23 in mg (around 600 mm mg). It makes sense.
