No. Do not do it. If the PCM cannot dump boost, it has nowhere to go and can do some serious damage to the valvetrain. This process should only be used to see if the BCA is working properly.

The topic it was in was saying it can't hurt anything. It just builds boost sooner.

You can build boost sooner by optimizing the position of the BCA..

You can detonate your engine by bypassing the PCM'* control of boost.

That'* way out in left field. The BCS BYPASS is a different Mod.

The BCA adjustment is different. Yes, it can get you into boost quicker, but only by milliseconds. You're not likely to feel it. For those going for every .01 seconds on the track, it might make the difference.

Loosen the two 10mm bolts holding the BCA to the SC (you will have to remove the BCS to access one of them).

Rotate the body of the BCS COUNTERCLOCKWISE, hold it there as you re-tighten the two bolts.

This should take 2 minutes.

I don't totally agree with that. I adjusted the BCS to its "optimum" spot, but I was gettin too much boost too quick and gettin' KR. I just undid it all the way, both for economy reasons and to help eliminate KR, and it actually takes a coupla seconds to build full boost now. No more KR.

Series 1 and Series 2 are distinctly different. Our BCA'* and brackets aren't the same. It might explain our different feelings on the adjustment.
