running rich and slower

i just installed an afpr and a 52mm throttle body its running rich and is slower is this because the fuel pressure it too high. Would that cause the car to go slower please help

what is your FP set at? also a 52MM TB is too big for a stock 305...

Check your fuel pressure. My car runs the best with the stock 42 PSI. Many people crank up the fuel pressure and go slower.
