Whats the ball park price of the PC-V? I may get it in the spring in spite of my warranty concerns.. I have installed an Oil Cooler and already switched over to full synthetic oil, so first I'm going to see just how hot the bike runs. harley maded these bikes to run hot, at 14.7 a/f ratio which is street legal. So, if the ratio remains in the 14.7 range, how bad could it possibly be? SURE adding a controller makes it run cooler, but it also makes the bike tecnically illegal and can likely void your factory warranty. I may live with factory range a/f if I can do the mufflers and live with it like that.

In the "TECH" article, they take a stock 2009 Street Glide and do a step by step install of D&Ds Boss Kit which is comprised of D&D Boss slip on mufflers and a Zippers high flow air cleaner assembly. The end result is a Dyno run that shows an increase of roughly 7 H.P. and 5 Ft. Lbs of Torque. The dyno run sheet is published and here's the interesting part.
No modification was made to the EFI itself, no aftermarket controller and you know what? The a/f ratio was good throughout the entire dyno run. The ratio barely went over 15 between 3000 and 3800 RPMs and I mean barely. The rest of the RPM range was at normal, between 14 and under 15.
Does this tell us that we can do these mods without installing EFI add on computers? It certainly seems to. To me, this article is eye opening... For those of us who don't want to jeopardize our factory warranties, maybe this is the answer. I just ordered new slip ons, not I gotta' look for one of these Zipper air filter assys.

The factory EFI has some "learning" capability and perhaps Zippers/Boss has figured out the max of that capability with this combination.
As for the factory warranty, any device which changes or effects the fuel/ignition timing is a potential warranty issue (and those changes include exhaust and a/c) if you experience heat related damage.
Also, did the article say anything at all about pinging; i.e. did they use an SEST or TTS Mastertune device to note if the engine had any knock?

I was told by a harley mech that works at the local dealer (who just happens to be a friend of mine) that the newer, 08 and 09, have better "self" tuning capabilities then the older EFI, due to the way the 02 sensors work with the new ECM, and that they will pretty much never go lean the ECM will see the lean condition and compensate to eliminate it, remember when the lean conditions accurred and store it so it won't happen the next time. but that just means it will keep it around 14.7,

I just hope you don't like the chrome on your pipes and don't get caught in traffic if you are going to run pipes and a/c without something to tune it. I ran just pipes on my 08UC for about 1k before i picked up the SERT. It burned out the packing on the right pipe and now the chrome is yellow from the clamp back 2" and there is a nice yellow spot in the middle where the packing first started burning out. The question will be how much more heat will you have when running just pipes and a/c.
I say give it a shot and see what happens. The 09s might work better. My little mistake cost me the good looks of 1 pipe and i can live with that but i wanted to get it right before i buy another set.

Your "ADD-ON" computer does just what a good Dyno tech does. It remaps the system. do you need it? NO! if you have the bike re-tuned on a dyno, those add-ons are not needed.
Friend has done this on his bike, and his wifes. Put D&D FatCats on both. His is a touring bike, hers is a fatboy. Both run great at any speed. Heat is NOT an issue, and no popping on De-accel.
He is a rider...he averages 25K per year, and has had this set-up for 3 years. Engine IS built up to 103.
The add-ons simply allow you to avoid having the bike remapped on a dyno.

I have added the SE Street Legal Performance Pipes and the Ness Big Sucker Stage II to My Bike without a Fuel Pack/Management System and the Bike Runs Great, I have No problems at all, why spend the extra money when you don't have to.

Is'nt that about the same you get with a just plain old stage 1 kit? Seems that is like the way to go. I have never had any heat issues in 15000 miles tah made me jump up and try to re engineer the bike. The only heat I have a felt was being stuck in traffic at Laconia, then I just shut it down.
