i just bought a new set of bigshots for my 06 heritage and the factory pipes were blue when i was taking them off to put the big shots on. Does this mean the mixture was already to rich and will i need the remap for these pipes?

You should be putting on a PCIII regardless.
I had an '04 Heritage and loved it with the BSS. Even more so when I could throw in the alternate map and run without the baffles. The bike will run so much better by adding the PC.

And by bluing the pipes....do you mean the headers themselves, the heat sheilds on the headers or the mufflers? If it's the headers, don't worry about it.

You mean too lean, not too rich. Harley's AFR, especially on an 06, is set pretty lean for EPA. And yes, you will need a PC or SERT if you dont want the blues and you want the bike to run better. I wouldnt run the new pipes till you first get the AFR correct and I wouldnt rely on a dl from HD.
