What exactly that tunning will consist in? I've called a place and they were going to charge me around 2000 bux for that, I didnt buy the N2O kit for that crap, what are my options?

I hope $2000 is a typo as that's insane. There's a few things you should check that were already mentioned. Timing is important as is your A/F ratio (both at WOT obviously). You'll also want to make sure you rev limiter is where you want it (don't want to bang off the rev limiter and have the pcm pull fuel while your nitrous is running).
