I had the PCIII on my last bike. No problems at all. Now I have the SERT because the stealer was really pushing it instead of the PCIII. [:@] If I had it to do again I would go with the PCIII because as maineultraclassic said it's much easier to work on if you make a change to your setup. WIth the SERT I have to take it in to the stealer and fork out $150 for every new tune.
use the one your tuner is good at if you are geting a custom map if not get the pcIII
That is a very good point!
I have had PC's on three EFI Harley's and never a problem. I have also installed them on several bud's bikes w/o issue.
If you're really wanting to mod you engine (more than basic pipes, cams, big bore, 95", port/polish, etc.), you should consider the Daytona TwinTec Dual Channel Closed Loop system.... Otherwise, PCIII has been great for me.
