borla hush and titek catted dp
i put the borla and titek in a few weeks ago and it was boosting about 13-14psi and was holding. a couple of days ago under WOT it would hit 15-16 and go down to less than 7.5 then back up to 14 and hold.
today going about 2/3 throttle in 3rd it hit 3000rpm it would boost to about 17 then drop and spool up normally to about 4k then it would spike to 15-16, drop then it would hold at between 13 and 14.
ive checked all the vaccum lines. all the lines are tight and undamaged. i havn't adjusted the wg arm.
the car ran perfect after the catback and dp. no problems untill a couple of days ago.
can someone point me in the direction of what i could be, or possible fixes.
