I have a cheap manual b/c that just screws in and out and stays in place with a locking nut. I turned up my boost today to 12psi and took it for a run. In all my gears the boost spikes up to 12psi then falls to about 9.5-10psi. My EGT's where good and never went over 1500-1525 deg. My question is can or should I turn the boost higher to like 15psi so when it falls it goes down to like 12-13psi. Now I know you should retard timing at 15psi but it would only be there for a sec. I am trying to get my hands on a profec b to replace my mbc so I will end this problem but not for a while. Let me know if this is safe or not.
