I already searched and found similar threads but nothing specific enough. I just got the NX  single Nozzle system. I am putting it on my 2000 Civic EX. The only underhood mod I've done so far has been a AEM cold air intake. One of my friends at school (i let him do this without thinking) put a jumper wire on my ECU and advanced my timing 2 degrees, he said. The car runs fine, but I want to know will I encounter any problems with the nitrous and the timing change? Also what spray can I use? NX recommends I can only do the 50 shot, but I've read a lot of people hitting a 75. Any thoughts?
