So ive got a Street Bob and I think it needs drag pipes and that K&N airfilter, so ill need the SE backplate, K&N, and the cover plate, right? (if you know part numbers for that stuff, please do post)

So i need PCIII, and the pipes and the airfilter. So my question is, how hard is it to intall the "chip" and if i install all that stuff and RIDE it to a shop to get it tuned, will it mess up my motor?

Thirdly, who makes a good drag pipe? How are Sampsons? I want this bike loud, dont bother flaming me if you dont like loud bikes, i do, it drows out the crap being played in the car next to me.

 

OK, Lalaman what type of pipes you prefer is up to you, we all set our bikes up according to our own preferences. That’s one of the big draws of owning an HD. We do scope out the accessories and modifications on each others bikes and sometimes incorporate them into our own or even modify what we see to suit our own tastes. That being said, the PCIII is not a chip, it is an electronic module about the size of a deck of playing cards. When you order your PCIII, many if not most, venders will ask about your engine set up (intake, exhaust etc.) and will load an appropriate fuel map for you. If they will not do this then find a different vender, or if you know how to down load files and move them around you can just go to power Commanders web site and down load the map that most closely matches your configuration. With a map that matches your engine configuration fairly closely; the bike should start and run ok. But if you want it to run up to its potential then you will need to have it dyno tuned. The unit will come with installation instructions and the install is not difficult. Can’t help you with the drag pipes but I am sure that others on the forum can.
Try www.fuelmotousa.com for a PCIII.
Good luck with it.

But with the PCIII it will allow me to NOT to keep the 02s correct?

So is there any "chip" b/c people have been telling me I need a chip? Im kind of confused b/c I have been reading this forum and did do a search. It just seems that with the newer FI models very few people are running drags on them right now, so I want to set it up correctly. I know im going to lose some power, but id like to keep that loss to a minimum.

 

The “chip� that you refer to is most likely the flash or down load that the dealer will try to sell you if have the SE Stage I air cleaner dealer installed. It will cost you about $150.00 for the flash, some have it done and some say that it is a waste of money if you are going to get the PCIII. But sure enough get one or the other or both, if you have plenty of bucks, because the TC 88 engine runs kind of lean to begin with and a freer breathing intake and freer flowing exhaust will make it run really lean. This will make the engine run hot and it already runs hot enough as it is. The idea behind the PCIII or the dealer flash is to remap the EFI fuel map and richen the fuel load which will be nessairy because of the higher volume of air flow with the new intake/exhaust but as a side affect it also cools the engine some. As a side note, going with the flash only will still leave the engine running a little lean. So the smart move would be to get the PCIII as its far more configuerable and a good tuner can make tweaks and adjustments to the map.

Oops! You also asked about the o2 eliminators and yes the PCIII will come with o2 eliminators. (And before you ask)They are small hardware devices that plug in to the o2 cables that are connected to the EFI module.

Drag pipes will make it run rich on the bottom and lean on the top. As long as you know you will lose bottom end and are cool with it as you stated, no problem there. The reason the bike will lose power and run richer on the bottom is that the drag pipes do not scavenge until they hit higher rpm's. However, the ECU is programmed to deliver fuel for a pipe that is scavenging well on the bottom end. Thus, you will most likely remove some fuel with the PC and add some on the top.

 

But after all this is installed I take thje PCIII to a speed shop with a dyno and they can tune it for me? Or can I just download all the stuff myself?

One speedshop I talked to said stay away from Sampons, but maybe that is b/c they dont carry Sampsons.

 

Well, some times you can find a fuel map that is right on the money but even on two engines set up exactly the same. There can be manufacturing differences and tolerance variations that would prevent the same map being a perfect match for each one. Luckily the generic maps are close enough that if you look at the build combinations that the map is created for you can find one that you and the engine can live with. But a dyno tune will tweak the map and customize the map to your engine. (Again can’t help you with the pipes).

Loud bikes are fine with me (I run drags on my '76 XLCH, but then again, it's a race bike), but I can tell you right now that it will run like crap on the street if you run drag pipes. There are plenty of good exhaust systems that are plenty loud and still perform well. Try the V&H Straightshots. They offer a good compromise between loudness and low end torque. With open pipes of any kind, you bike will be a dog below 3500 rpm or so. You can also damage your heads. Reversion will cause cold air to be sucked back into the head potentially causing thermal shock. Every engine needs some sort of restriction in the pipes to make them run well. Another drawback to open pipes is that it will be VERY hard to tune correctly. I can never promise a customer that their bike will run good if they insist on running open drag pipes. Drag pipes for the drag strip.... period.
