I've just installed a SAFCII. I am going to install a MBC sometime soon.

Does it make any difference tuning the SAFCII with or without a MBC??

 

Are you on stock injectors?

 

yea as long as you dont have upgraded injectors work with more boost and ect. Do you have a boost controller

 

Yes, I still have the stock injectors. So, will I need to change the AFC setting when i have a boost controller??

 

AFC's and MBC's are like bread and butter, Sunny and Cher, Jack and Coke... they just go together. A MBC is more desirable because it holds boost better than the ECU, no tapper, and rocks up faster. You can tune on the stock solinoid, but a MBC makes tuning the AFC easier. Set your MBC to your desired boost (make sure you have a logger) and tune away;

Injector size is a bigger factor when tuning the AFC. That's why I asked.

 

Thanks... ordered my MBC already... should be here anyday now..

Will install the MBC before tuning the AFC.
