this is a good time to advise for everyone if running nitrous or not, one of the best tuning aid is an air/fuel gage.
i bought an aem gage.all i did is welded a bung on collector and plug er in. thats it,now i can tune my 3 circuit dominator with it. for around 300 bucks or less perhaps,i paid 260 to my door,awesome investment!!!!!plug a camcorder on your roll cage and record.enjoy!
