I'll let you all know in the next couple of months on the difference between the the T-Max and the S.E. Race Tuner.
I've got a bro. with basically the same bike as mine and I plan on comparing 'em. He's got an '07 FXSTC with stage 1 S.E. air cleaner and Rush slip on exhaust, and a S.E.R.T., and I've got an '07 FXST with stage 1 Arlen Ness Big Sucker and V&H Big Radius exhaust and a T-Max EFI unit. So far I've only been able to log a couple of hundred miles on the new tuner but the weather's getting better so it's about time for a road trip:bigsmiley11:
