Welcome Aidian. Lots of great info and people on this forum. You will learn a ton if you so choose!
If you want to have someone else do the work at least for now: the most reliable shop with the best reputation is by far and away; Burnaby Kawasaki. No; I don't work for them, I'm only a customer and it's not just my opinion.
The best solution to get everything as good as can be out of your fuel system & tuning is to take it to a Dynomometer. One of the best if not the best is Michael at MAS in Langley. He is the main dyno tuner for our local racers. Give him a call to find out how he might help you. Here's the web link:

Another local tuner with a dyno is Murray. I'm having a brain fart and can't remember his contact info but when I find it I'll pass it on.
If it were me I would start with Burnaby Kawasaki if for no other reason than to start a relationship with them. If you're already a customer there I say with 100% confidence; you are with the best dealer.
Good luck with the tune!
