OK guys, car is up and running, not leaking fuel nemore.. 2nd fuel rail is hooked up and kickin in.. Anyways, i think my boost guage is faulty so heres where i need help.. i have a 3-bar GREDDY MAP sensor hooked up.. when i have ignition applied it reads 1.50v.. when i start car, it goes to like .60-.80 ish.. then when i was test driving it, i got it to like 1.80v? is there a simple convorsion to turn that into psi?? or am i screwed.. lol.. i just dont think the boost guage is working cuz it stays in vac range and doesnt go past like .5 in vac, but feels like boost..

help thanx. i just wanna convort it to make sure my waste gate is working.. thanx..

 

its autometer sport comp.. it reads vac but not boost.... so shouldnt it be hooked up right?? i duno.. i think its faulty cuz i got the absolute pressure sensor reading, and im building boost.. like 3.5 lbs.. woot.. i think my gate is opening too soon...

 

my absolute pressure is hitting 0.30 bar and i think the gate is opening and it wont build from there..

 

yes, from the software.. and its getting that from the MAP sensor..
