Looking to upgrade cams in the future. I am not sure whether investing in a PV would be worth it if the SEST came with my bike. would the tuning be noticeably different?

I don't see myself doing much more to the bike after the cam install. Has stage 1 with 2-1 exhaust. Is it worth dropping an extra 400?

Thanks.

 

If your going to stick with HD parts only you will be fine. Sure you can get a better tune but is it worth the $400 + in cost to you? Now if you plan to go aftermarket cams and exhaust then a better tuner like the PV or TTS would be worth it.

 

I don't have warranty so I plan on getting aftermarket cams.

 

can't go wrong with the PV and a descent few runs on a dyno. The SEST is a street tuner, it maps for street, so you won't get the full potential out of the upgrades you get.
thoroughly research your cams. many different ones out there, if your gonna spend the money, find the one the best suits you and your riding style. low end - top end - med can make all the difference on how the bike runs. Nothing worse in spending the money and time into something then have it not quite what you want.
