It would seem to me that if there's anything to be gained from the xfi, distributor, msd arrangement, it's going to be due to the msd box. Certainly not because of the distributor. If that's the case, then why not just go with a DIS system that gives a hotter, longer spark? Now you're just going to add cap and rotor wear to your tuneup list, and have to periodically check for distributor gear and shaft bushing and endplay wear. A few more points to add to the inaccuracies of a distributor system.
