[famouz13]

ok guys, ive searched and searched to figure this out but to no avail, so here it go's. i bought a ebay intake and installed it on my 99 gs-t. it was fine at first like like city driving. then i got on the freeway and it violently cut out at about 3-4k, i reinstalled the stock intake and took a good look at the ebay intake, i noticed that it lacked a dump tube"it had a spot for the for the dump tube but no tubing inside the inkake" i went to the hardware store bought some pvc pipe and jbwelded it into the intake according to a VFAQ , then reinstalled it and checked all vac lines, MAF sensor all that stuff plus everything else, but now it's not near as fast and the BOV is really quiet also it still stalls every once in a while .... any help would be appreciated
