IF your engine is suffering from leaning on heavy acceleration then it MIGHT benefit from the increased fuel pressure of the XR6 regulator - keep in mind that we're not talking about a massive increase in fuel pressure here.
Unless you have the car checked out on a dyno with gas analyser to determine what's happening first, then the only other option is to get an XR6 regulator and try it - but be prepared that it may well not do anything for you (may even cause loss of power) and may end up being be a waste of money - experimentation is never a waste of time.
IT'LL GO OR IT'LL BLOW!!!
