so i have a A55 on my streetmate obviously. my question is, i have a number 65 jet, and a biturbo. i was seeing if i would see any performance by taking the stock air box off and run it without an air box. when it hits second gear and i give it gas it bogs down and wont go faster than 20 mph. but does fine with the air box.
i figured since the stock airbox is restrictive it creates more suction on the fuel. so i adjusted my needle since its sucking more fuel in with the air box on to see if i can go faster. dont know if any of you had this problem or something similar before. thanks
im looking for a 19mm carb that i can tune with low speed and high speed needle jets. i HATE JETTING.
