The other day i installed an adjustable boost elbow. I went today on the highway to try it. i made 29 psi first couple spool ups 5th gear WOT. Its ok for 5000 ft elevation i pulled over and screwed the set screw in 1/8 of a turn to see if i could get more boost. i went again and it spools up but then the waste gate opens and only spool to 20psi i pulled over about 4 other times moved the screw in and out but nothing still 20 psi. I then screwed the screw in all the way to get no air to the wastegate and still only 20psi. I got one exactly like the pictures. any help???? thanks mario

 

Dose it have a vent hole in the side? if not it will only allow the boost to rise for a short time until the pressure ='s out on both sides of the restriction. If it has a vent on the w/g side of the Allen head it will vent off some pressure and allow it to stay at a higher boost level. I make some like that the same as TST sells. If you turn it clockwise it should increase boost if you have enough fuel. I put a EDGE COMP ( 120HP like your Attitude) with AFE intake and a full 5" to duel 5" stacks that I made and his would only make 30psi. Also check for intercooler boots that may be leaking, he blew his off 2 times and I did it once at 36psi on my 96. The clamps are not very tight from the factory. Check to see if the Attitude is backing off for any reason like high EGT's in the thin air.
