if I'm cruising at city speeds like 30mph and i step into the throttle to wot i get a slight bog but when im cruising at 50mph or higher and i do the same i dont get a bog and its very smooth.

So i'm thinking i need to change the pump shot but not sure exactly which way to go with it (sooner vs later or more vs less)

Buy the Blue cam and use it. Keep the squirters small if you can, tune with the cam first. You'll have to tune to the spring as well. Try one thing at a time.
I would have gone to a 3.5 PV personally. It sounds like you have the idle circuit lean...maybe 1 or 1.5 turns out...try 2 turns out and bump the idle up or at least 1000rpm and see if that helps.
