Ok i am looking to get a 75 mm throttle body and i was wondering if i will have to upgrade my injectors and fuel pump if i want to install it. the mods i have are underdrive pullies, 5% overdrive pulley, exhaust with no mufflers or resonator, 73 mm MAFS, and a custom cold air intake. I dont really know if this will be close to having to upgrade but before i buy it i just want to make sure. cause i dont have any head work done so i heard that without that done i cant really even make close to 300 hp which is the limit for the new injectors and fuel pump. but please any help on this would be greatly appreciated because i am stuck as to whether or not to get it now. thanks
Matt
