I have been thinking about going to the Stage II Big Bore rebuild with my 06. When I talked to my service manager at the dealership, he thought I would get more bang out of my money if I waited and did the true duals,PCIII, Stage II all at the same time. He would only do what your talking about if money was an issue and you werebuilding stages to get to a big bore engine. His reasoning is you will have to retune your bike with each stage of the build and dyno time is not cheap.

 

nope, I'm not changing exhaust.

btw, that's what I'm hoping for with the PCIII, a cooler running bike, cause it's so lean at street speeds, even with the download. I'm hoping the pinging problem is helped also, but that seems to be hit and miss.

 

I've never had any pinging. Are you running premium? I think I'm going to go ahead and do the PC just for the fact of improving the lean running condition also.

 

I've got a SE A/C and the older SE slip-on's with a PCIII on my RKC. I've not had it dyno'ed so I can only give my impressions. I may have a little more umph but the thing I like most is how smooth the bike runs now. No cough's or hesitation when starting up around corners. I think it was worth it.

 

yes 91 octane fuel, the highest available.

 

I presume the effect will be close to the same, because the 21 has higher lift, longer duration and the intake closes early compared to stock cams, but I don't know that for sure. Give Andrews cams a call and they'll help you.

 

Does anyone else out there have a PC with the SE slip ons? Are the SE slip ons really that much more restrictive than the rhineharts or V&H? Once again, Eastern Performance is telling me so.

Thanks,

Dave.

 

Skateboard,

Was that 4 hp and 2ft lbs increase from the PC? Or was that including the a/c and slip ons? Did you already have the ECM download?

 

when I went there I had the pc111,slip-ons and air cleaner on the bike with the map Jamie down loaded on it.after the tune I gained the 4 hp,2ft lbs.[/align]

 

Ok so you gained that by tweaking the map a little more.

So far it sounds like there really isn't much of a difference between the HD ECM download and the PC III. At least as far as power is concerned. I'm really surprised. I would have thought that being able to tweak the injection map to your hearts content rather than what the EPA wants would make a big difference. Sounds like the power is already close to maxed out without doing some engine work. Does anyone have another conclusion?
