Ok...I got a little insight here...
Steve...is this the same broken boost solenoid you were trying to fix the other day and figured out it was broken and needed replacement? If so...please..don't measure performance with this broken piece of junk...wait til the new one comes in and you bolt a fresh clean well working one onto your baby. Then hit it and see what it does. Bet you are really happy.
yep!!!! trying to gauge off a broken part is only going to leave you with broken readings. I just earned one of these
Plus..I've got a little test for you. Turn your key on..but don't start the car. Where does your gauge read.... 0? or a little one way or the other. Mine is a little to the left (vacuum) side. Which means that even if my gauge (remember all gauges are only reference...not perfect) reads 7 pounds..I'm really closer to 9-10.
The gauge is a reference...use it to see the boost is working and let the car pushing you back in the seat tell you how much boost you are getting. Some call it there Buttometer.
