RE: Slip-ons - Re-map necessity?
I put the Vance&Hines slip on ovals on my FLHXI and did the Screaming Eagleair cleaner and the Vance&Hines Fuel Pak. I seen this on their web site and then I did a search on it here on the forum. The dealer told me you put the fuel pak on instead of downloading a map. So the cost is not that much of a difference (the fuel pak if you shop around will be about $240.00 and a map download is about $150.00). So far I have not had any issues.

RE: Slip-ons - Re-map necessity?
What a coincidence. I installed a set of Samson Silver Bullet slip ons this past Friday 7-7-06. No other mods, no PCiii yet. Bike runs and sounds fantastic. Revs up a lot quicker, pulls a lot harder, better instantaneous throttle response, looks very similar to stock with the taper cuts (except a little smaller diameter), oh, did I mention it sounds killer?

I just installed a set of Wild Pigs slip-ons on my '06 Ultra. The rest of the system is stock so I haven't done a remap. The bike sounds fantastic and does not have any decel or popping. I was looking for a low deep throaty sound and these pipes did not dissapoint. Very happy with them.

I am still confused. [8D]
It makes sense to me that changing the exhaust does not change the air intake therefore does not lean it out any further.
Or does the fact you are allowing more pressure to escape - it allows more air intake - resulting in leaner conditions?
Then tonight I am reading the July issue of AIM "HOG HELPLINE" - page 192.
The Question (condensed version) - 2003 Fatboy, 15,000 miles, at 11,000 miles he installed V & H Longshots HS Exhaust. He inquired at several H_D Dealers if he should re-map. He got several different answers. His question to "Helpline" - "Exactly what (if anything) would be damaged?
"Helpline Answer" Changing the exhaust system to something with less restriction will typically lean out the air/fuel mixture. At cruising rpm, the engine starts to run hotter than normal and can get to the point of overheating. If it gets bad enough you could cook the oil and stick a piston. The 03' mapping wasn't as picky as on the newer models, and you could run sertain exhaust systems without any other changes. Your best bet is to have the air/fuel ratio checked and go from there.
Regarding the engine running hotter - on my 06, the heat coming off the engine with the stock pipes was nearly unbearable on the bottom of my upper legs. It feels about the same now.
With heat being such an issue with these motors I really wished the MOCO would of put an oil temp guage on instead of the useless Air temp guage.
I will be installing the K & N & PCIII in a week or two. I was hoping to keep the V&H Ovals on until then.
Do I understand - Once I have the PCIII installed an H-D re-map is worhtless?

I installed an oil temp gauge so I'll keep an eye on it to see if the engine runs any hotter than normal with my slip-ons.
