Do they make them for our twin blade throttle bodies? I cant find them.. and are Underdrive pulleys even worth it with the bullitt? -- I have JLT CAI (pita to get to the filter to clean btw), Mac H-pipe O/r, and short throw shifter.. im looking for a prochamber and shorties atm but looking for other small/cheaper side mods to squeeze some more powerr out. Any input from bullitt owners is good input.. Thanks, Steve #4041.
