Default Biggest gain?

UDP, Accufab 75mm TB/ Phenum, Stewart Water pump, ive heard 12-14 hp for a 150$ mod. Which would give the biggest noticable gain.

99GTkevin, if you can afford it go with an intake manifold+t/b+plenum and get you some noticable power gains, like 25-35 RWHP

im not sure either ive read other forums where people have gained 12-14 horsepower with the pump and aftermarket pulleys, because its only suppose to use 3 horsepower to run it. Its suppose to flow better also.

water pump adds horses cuz it takes less to spin it taking away less horsepower from the rear wheels. adding more horses
