Hate to call people out but a lot of ignorant posts here - Manual Boost Controller are very effective and most modern CPU's can compensate for the increase in fuel needed to run them safely (evo for example) they also often build boost quicker than solenoid controlled systems
Am i going to run one on my 335? absolutely not - I'll let someone else figure out what's a safe boost threshold, that said MBCs are the meat and potatos of turbo car tuning
