im running 7.8-8.5 psi on my B20B with a large t3/t4 and zdyne stand alone. It just doesnt seem fast... i dont know why maybe its just me it put down 182 whp at 5psi at 5900 rpm and should now do alot more due to a more tuned base with alot less timing pulled out. Any ideas or is it just me

 

I made 226/195 on 6.5 psi b20b b16 head, untuned with a clusterfawk fuel system. Do a leak down test and see if the problem is internal.
