Does this require anything other than the ecu flash? I've seen some threads where they are using some GM components. How reliable is this in comparison to a mbc?

 

ECU boost control does require some mechanical modification ... at least replacing a vacuum line or changing a restrictor pill in another line. That is all though. the GM solenoid is optional.

Tuning the stock solenoid/GM solenoid is the tricky part. They like to spike and the boost can "yo-yo" a little if your error correction tables aren't correct. But, once it's tuned, you can usually hold a little more boost up top than a standard MBS because of the active nature of the solenoid.

You can also dial in your desired boost curve ... an MBC will almost always make a flat curve till the WG can't hold itself shut anymore.

 

What's your recommendation for the guy who will just have their car tuned once? MBC or ECU boost control. Thanks for your input.

 

Mbc.

Instead of getting an MBC, you should check out the results of this little test I did:

When I tune my car from a TBE w/cone filter to adding an MBC what do you think I should be looking to change? Should I be tuning gradually (tune at 10, 15, 21) or can I raise my boost to the desired level (21PSI) and tune at that?
