Put on my MBC today, set to 14psi. Now i get Boost creep in the upper RPM's right before I shift, I let off soon as it hit 16-17 psi. Time to port the 02 housing? Is there any write-ups on how to do it or where to port? Ive never even had mine off.... Pictures would be great. Or how to do the Dump tube mod? Ive got a Die Grinder, Welder, and I work at a machine shop so the porting and fabrication are no prob...
