6.0 370ci d1sc problem I have just finish putting my motor toghether on a 94 Silverado it’s a fully built lq9 370 with a procharger d1sc with upgraded Jon bond performance impeller truck running strong but I’m only seeing 7-8 pounds of boost on gauge on a 2.8 pulley I did do 8 rib set up to help prevent belt slip . Does 7-8 boost sound to low, seems very low to me ? Any help to help me diagnose why boost so low. I have checked and found no leaks on piping or intake manifold

What's your crank diameter? Need to know how hard you're spinning the blower. Pulley seems small and might slip. Does it have a good belt tensioner? What kind of belt wrap does it have?
