Default what is it?

I have an 05 RKCustom, when I'm cruising around 65 & put it under a load like going up a hill or roll on the throttle I had a high pitch chirp, so I did some research & found from here that it was probably in the fuel. So I went out & got me a PCIII, it took away most of the chirp, I put the download on it from their website, however I still have it under some conditions, same hill or rolling on the throttle more than usual while under the load of going up that hill. Response seems to be definitely better than what is used to be before adding the PCIII. Does anybody have any idea what could be still causing the chirp? Do I need to tweak the fuel setting some more? This is my first FI model. Any ideas would be appreciated.
