[QUOTE="NotoriousGT350, post: 3652816, member: 30048"] When i dynoed mine earlier this year with a IV port and same pulley combo, I had seen boost up to 18-18.5psi, then drop to 14-15 after 5000rpms. I'm getting belt slip and my a/f ratio on my Wide Band has been going from 11.6 a/f to 10.3 right around 5000rpms and up. I'm seriously thinking about just switching to a 2.93 upper with 4-piece BF idler setup. I'm tired of losing boost and power up top where I need it. My numbers were 490rwhp/522rwtq. I have 60lb injectors and BAP set to 0%. I know I have a lot more in it. Let me know how things turn out. J.R. [/QUOTE]
