Get it on a dyno and have someone who knows what they're doing tune it. I find engines are too expensive to risk messing with without a fair bit of tuning knowledge.

"initialize" everything.... setting everything to zero is even worse advice.

Getting it on a dyno is useless without hooking up your car to a wideband O2 sensor. Without it you're wasting your time and money.

Most dynos have a inhouse wideband sniffer

Yeah, it is possible to tune it yourself if you can set up your own wideband 02 sensor, me and my mate did on his SiR2 Civic, seat of the pants it felt quicker, but we were paranoid of hurting the engine so there was always way too much fuel going in just to be safe. Leaning too much is not a good plan.
Only real way is to get it on the dyno.
