timing question

i race a 1990 integra ls with a b18a and a friend of mine told me that if i advance my intake tiing two degrees and set my exhaust at 0 this would make my car run better at the rpm range i run ( 5500 - 7300) is this true does anyone know and could anyone see this causing me problems? i am not to knowledgable about these things so any help would be appreciated. thanks Chad

Unless your engine is highly modified, aka not just an intake…you will never see a notable difference from advancing your timing, except that you will have to buy premium gas…
