Sorry for being so blunt with the heading, just need some help. I'm having some issues with my car such as my boost is only reaching a max of .05 mpa in each gear full throttle. I was told that it is supposed to reach around .08-.09 factory boost. I have looked over all my hose on the TMIC and also checked the boost lines and so fourth. I didn't see anything cracked or off of anything else. Also after the car is hot and has been driving around for just a bit it every once in awhile idles pretty rough. Like a bum bum bum bum kinda idle that you can actually feel the car shaking/vibrating or something. It doesn't change rpm's when it does it it just idles a little rough. I did take it to a shop a few weeks back and the guy at the shop took off the TMIC and fixed some intake hoses that were not seated properly he said and he also lastly changed my boost lines saying the ones on the car were completely wrong lines. (My car was running lean and stalling out thats why I was at the shop by the way, there wasn't a boost issue then). He said he put a restrictor pill in the boost line as well that he said wasn't in there and it needs to be in there, :/ no clue what that is lol. So the problem now is after he did all that I'm only pushing .05mpoa full throttle in every gear. IDK what the issue could be. Could it be that restrictor pill causing that? Is that supposed to be on this car? I did notice though that the vacuum line going off the T to the side of the car where the wasgate valve or w/e it is is 2 hoses connected together with a little gray plug, is that supposed to be 1 solid hose or 2 plugged together? Any help would be highly appreciated, I can't stand not being at maximum factory boost, it's no fun.
