I have a setup almost identical to yours but mine is a 03. 5 (305/555). Is yours a 305/555? I have the Xcellerartor, Edge EZ, and Tst (non-twins box) with my setup. What setting do you have all of yours on and which ones have you got the best performance from? I removed my ez and made the truck get off the line faster, but lost mid and top end.
