I have a 2009 Nightster with Rush slip-on exhaust. The bike sounds great. Not too loud, not too quiet. I have noticed that it could use some more fuel. I have done some research on the TFI and have not read anything bad about them. I ordered one for my bike and am expecting it next week. Does anyone have any good or bad information concerning this module? Any advice about installation as far as what to make sure to do or not do? Anything of that nature would be greatly appreciated. Looking forward to getting more performance from my bike. Not trying to spend a ton of money, just want to make it run efficient and last longer. Thanks.
