FI tuner
Thinking of installing V/H tuner on my 09 Fatboy .Will I notice a difference with stock exhaust ? When I get a little more money together I will be doing exhaust also. Should I wait to do both at same time? Thanks

I put a Power Commander on mine while I was waiting for the exhaust to come in. I noticed no real difference. I then put a K&N air filter in and noticed a difference at higher revs, it wasn't struggling as much. When I finally put the exhaust on it ran great.
If you're going to put the Fuel Pak on, I would suggest springing for a new air filter as well. This will get you the most bang for your buck. I believe a K&N is around $70.

There is no need to waste your money on a fuel pak or any other system until you are ready to;
1. Put on a larger intake (note... more air IN)
2. Put on larger exhaust (note... more air OUT)
Placing a fuel management system on a stock bike without mods to the intake and exhaust doesn't really buy you anything.
That said, allowing the engine to "breath" with more air in and out, along with "richening up" the fuel/air mix will make the thing run like a wild chimp and run much cooler.
