sorry if this is in the wrong spot didnt really know where to put it.
ok so yesterday i just got my car back from the shop. i blew the engine and i was getting another one put in. no upgrades
and on saturday i got it back drove it around and it felt super weak, and i could barely hear my bov. i was thinking i was just used to the power so when i got home i was going to install my downpipe and flash stage 2. i ended up with stage 1 no downpipe install for now. i was monitering my boost and in 4th gear around 5700-6000 rpm i was only hitting 7psi?!?!?!?!?!?!?! anybody know what is wrong????? my mechanic had told me my turbo was fine so i still have the turbo from the engine that was swapped....should i swap them out or what?? any help would be great! thanks
