Default SE slip-ons/air cleaner/enrichener...What should my expectations be?

The stage 1 conversion is something that I will consider down the road, but not right now. I have a little money to play with thanks to some dealer credits and discounts that I worked into my deal.

Other than a little more sound, what should I reasonably expect in terms of performance with the mods above? Thanks in advance for any feedback.

Why would I even need the "enrichener/enricher" if the bike is FI?

With a canned SE map for my Power Commander, Cycle Shack slip-ons and an SE a/c, my EFI Sporty was making low 50's HP. But the canned map was very lean, so lean it didn't even show up on the printout I had. With a proper setup, I'd expect mid 50's HP. I've since had a conversion and the bike makes 83 HP now.

As far as an enricher, we like to call those tuners. You will need some kind of fuel management to richen the mixture after installing a free flowing a/c with free flowing pipes/slip-ons. One method is to use some IED's to richen the mixture. That is not a tune, it only allows the EFI to add more fuel keeping the bike from becoming dangerously lean. The other most popular way to richen the mixture is to buy a PowerVision for $500 then use Autotune Basic to tune the EFI yourself.

FYI:
mixture = the amount of O2 versus fuel in combustion chamber.
lean = too much O2 in the mixture which causes the engine to run hot (could damage engine).
rich = not enough O2 (too much fuel) to burn all the fuel in the mixture leaving unspent fuel in the exhaust (wastes power).
tuner = on board module or flash device that fixes lean or rich condition and adds power using custom map (or canned map).
map = electronic table of numbers that controls the mixture at any given RPM or throttle position.
canned map = preconfigured map that usually sucks because they almost never match anyone's stage one mods.

What can you expect? It'll be a bit more fun to ride and I felt it was noticeable. After stage1 tune, I ended at 59HP/52TQ. My tuner then allowed it to rev to 7k so it'll wind out higher than before making it feel more powerful too. Sporties love rpm's. Though definitely does not compare to the 1200 upgrade. I rode 2 virgin 2013big twin bikes last week. Slim with the 103 and a Superglide with the 96. My iron is a whole lot more fun to ride than them plus after riding them, I know my "girls" bike would kick their azz all day long I thought the 103 would impress me but no. Just the extra gear is a bonus to me.
