LEAK! ITS BUGGING ME.---Prochamber

Well i got my prochamber on friday and installed it today. Took me most of the day since i was pretty off by myself. well after everything was done i went for a ride, and i heard the wizzing sound. thought it was from the passanger side but couldnt really tell. after the ride i came home to check the bolts again. some were somewhat loose so i tihgtened them up... STILLL A LEAK!.... what do i do.! i have a 98 gt, heard of napa studs but not sure if i need them. HELP ME OUT!

thanks

Alright. I guess i'll have to do that. I really dont want to go back under the car again. kinda of a pain in the A##. I have ramps so it should be a quick process. Thanks again.
