Thanks for that, i had replaced the vac hose with the restrictor in it but changed it back shortly after, gauge started reading a little better once i did, but this is what leads me to think it may be a boost leak... or just dodge boost gauge in general.
For a bung in the intake could i remove the bleed hose on the bov pipe (not the boost sensor one) and block it off and dump 25psi down the nipple ( with tight commections etc
obviously)
We can get e85 over here but not at any pump, just by the barrel
