If youre talking about the OL/CL delay in the 04-05s, the 02-03s dont have that problem. MBCs are not completely horrible for the early WRXs. As long as the owner has a boost gauge to watch for over-boosting and part-throttle/full boost conditions it shouldnt hurt anything. Granted, some sort of EM is much better, but as long as you know what youre doing you can avoid problems.
