o crap i just realized... on the bbs i know u have boost/vac line in to the back with the one plug and i believe the bottom of the 2 front ones in to the acuator but where does the other one go?

well an update just got back from my trip pcm reprogrammed and everything hooked up every the bbs and i when 140 miles on 7 gals of fuel ... 20 mpg at 70 miles an hr ... but yesterday i noticed when the car was hooked up to the map sensor at 20 in hg on my aftermarket gauge the car read 12 in hg and at 10 in hg it read 18 at 3 psi it read 36 psi and at 9 read 49 sooooo im assuming the map sensor need replace .... hopefully after that the bbs will let me go over 3 psi at wot so that way i can tie in the vac line
