No, don't do that. Getting bigger injectors will probably just make the car slower. See my response in your lean condition thread.

My theory is that the black box retards the timing making the OVERALL tune safe. You would need to datalog to see for sure, or monitor EGT.

If you are going to spend money, spend it on some way to tune the car. I think you could easily pick up 15-20 HP from more agressive timing, and richer AFR under boost.

Again, you don't need bigger injectors.
