What is the sucker modification I have heard of using the PAIR valve ? Does it really add HP ?

ive seen post on it here b4...i was told it would add a couple HP but if you did and wheelies it would suck out of the case...dont remember where they said it would go...to the airbox or throttle body...anyway it wasnt good if you did a wheelie.

great if your engine is weak but I would save the 2.5# and throw it away
