Default Using Turbo XS ABC to Run More Boost With Cobb AP??

Will this work? We could only get 15.5 psi out of the stock system on stage 2. We adjusted the wastegate. We got the boost higher but in 5th gear I would get boost fluttering. Or should I just use a boost controller?

No idea on this one although the ABC should be able to help with a few extra PSI. You will need more fuel to handle the boost and keep your AFR's ok. I have no idea whether you AP can keep up with the larger change in boost.

Might be good to get some kind of control of the situation.

The ABC is an effective way of bleeding off air. Use it if you want.

since replacing the stock BCS & ABC w/ the GM BCS, my boost does not fluctuate w/ temperature....during winter it was always a constant battle w/ the ABC & the boost map to keep from overboosting...now I have had no issues... ...rocksteady boost...
