Subject: Re: Manual Boost Control Valve Kick --why?

I'm going to avoid the flame war here by not quoting anyone... Back to the thread: If you have an Abbott CPU upgrade then get rid of the MBC. It's one or the other. You wasted all the Abbott money when you put in the MBC. REMOVE IT TODAY. The Abbott solution is a much better idea as it retains normal ECU control and protection. If you want more boost than you get from the Abbott then you need to do some serious learning about performance tuning first. No exceptions. Second, I don't personally feel that an MBC is the end of the world. HOWEVER, and that's a big HOWEVER, it should be adjusted so that you never, ever reach fuel (overboost) cut off. That's what you are hitting now. Even with an MBC adjusted properly you loose any knock detection/protection. Other than that, I don't see that there is a heck of a lot of actual _danger_ to a properly set MBC without an ECU upgrade but I'll certainly listen to other opinions on the subject. Bob
