Hello everyone, i am new to this site, have been reading alot on here and there is alot of knowledgeable people and great info. I am new to HD bikes, started out with a Honda 1100 six years ago. Last year my fiance and i purchased a brand new 13 Heritage. Upon buying the bike we had RUSH slip-ons installed and that is it. I am am going to have the SE Stage 1 high flow air cleaner installed this spring and heard i should go with the PC5 or P-Vision, for the fact that i will be doing header pipes and 255 cams probably next year. i dont think i will ever do above the stage 2 upgrades. at the moment all i really am looking for is my engine running a little cooler and getting the bike to run a little better than stock. Is the PC5 or P-Vision good for future upgrades? Is it ok to leave the stock headers on , with just the slip on mufflers like i have now? My bike is still under warranty, will either of these units return my bike to stock setting if warrant work is needed, and also will i still have to have my bike dynoed after installing a tuner? Thanks for any help, and hello from Wisconsin.
