Well, i know my replies have been lacking here and i hate leaving topics unresolved, so some further information that might help others.
As it stands, there are two known issues.
1). Not causing my latencies or packet loss, but still needs fixing - my upload channels, i have 2 bonded channels, i should have 4 - the ISP is investigating the cause of this, the problem this causes me is two-fold. First of all i cannot reach my 36Mbps upload speed because i only have half the channels bonded, this in turn cases me an unstable connection during high uploads - I have temporarily fixed this by putting a limiter on my WAN uploads.
2). The ISPs router - the SuperHub 3 has apparently a bug in the FW which causes high latencies and random spikes (seems to have been rolling out since Feb/March), but only when used in Modem only mode and mostly noticeable with PfSense (since this is a common choice for enthusiasts) - I'm linking a topic relating to others and this issue. While this is likely to be a router specific issue, PfSense or BSD doesn't appear to help with this, if you leave the ISP modem in modem only mode and use another firewall, even a consumer grade router the issue doesn't appear to exist or at least not as often, changing the router back to router mode and double-NATting also doesn't show the symptoms, but this is not really a workable solution.
So, back to my original question, is there something or somewhere in PF i can log anything else that would be useful to anyone, to see if the OS or firewall itself is adding to this, perhaps a driver issue? (I am guessing, but trying to offer help at the same time).
Side note - last night i rebooted my router and i've yet to have the same issues, based on posts in the link below, this can sometimes be true for up to about a week. This suggests the modem is getting full and unable to clear itself, in modem only mode there is limited options, in fact after about an hour, i lose access to it completely on the modem IP.
While i am more convinced this is all related to a FW issue in the router after additional findings, is there anything else i can do or capture to see if anything in PF or BSD is related to this?
I've read a few articles that say this issue does not seem to be in 2.5, but i'll have to try and relocate those links again.

Post 4 in the above links multiple other articles.
For anyone reading in the UK, this seems to affect
SH3, with FW 9.1.1811.401 and possibly the SH4 for those on Gig
Both the SH3 and SH4 use Intel Puma 6 and 7 chipsets respectively, which have their own known issues, unfortunately in the UK we are restricted by the kit supplied by the ISP and have no options to buy our own modems.
If nothing else i wanted to keep people informed of the progress on my issues.
