Glad to hear about that solution, and 200+ rwhp is fantastic for that motor!
It has actually been documented for years, (decades?), that the quickest way to make an MFI motor slow is to install an aftermarket "sport muffler", either go w/ stock or factory sport muff. I wonder how many millions of hours and dollars have been spent by people trying to get the flat spots tuned out of that set-up, (MFI + Monty/Bursch/Dansk/etc...).
