Ive been chasing a low boost problem for a while now, and ive checked everything from vac leaks to gauge problems to egr problems. I checked everything that i thought it could possibly be and after finding nothing i decided that it had to be the super charger. I had my supercharger ported and i thought that maybe something happened to it during porting that was making it unable to make boost. So i finally bit the bullet and bought a supercharger that i knew was making boost. I put it on with the 3.0 pulley still attached and im still only making around 10 psi of boost.
Any suggestions on what to check would be very appreciated, even something off the wall that could be going on would be helpful. im at at dead end atm. I have a tech2 scanner as well that ive been using to monitor KR and alot of other data. I have 0 KR with the 3.0 making 10 psi.
Setup is a s1x cam, speed daddy headers, ported heads, and all other supporting mods, plugs, wires ect.
-Something else that is worth mentioning though is that i have my lower intake machined for an IC and im not running one. Im not sure if that could effect boost or not.
