its kinda difficult to tell because the video isnt the best..... arhh i dunno, think the best thing you can do now is get a boost gauge asap and run it like i said just to allow some testing to see what your getting boost wise, or i definatly feel you need to get a dyno asap ......

a gauge setup is essential to the general running of this kit imo..... i know i keep banging on about it but, right now youve been told youve got 6.5psi, for all we actually know that could be 5.5psi, really your shop shouldnt have let this car go without it showing the proper boost it was supposed to make..... 6.5psi is entirely possible on a 7psi pulley But i think id be asking why if their is another reason why im slightly down on boost, you actually may have a boost leak..... for the 50 bucks it'll cost please please grab a mecanical boost gauge and temp run it like i said, grab a passenger get on the freeway and do some runs and at that point you can make some decisions on where to go next....... this is the cheapest way to fault find and it also giving you some working knowledge of your kit as you taking things into your own hands.
