Hey guys I have a Bone Stock 2006 Evo MR with 40k miles with oem gauges(Boost,volt,temp). Im the second owner. I had recently put on Injen Intake and Injen IC Piping, and noticed two things, one when shifting the RPMs would hang before dropping down, and two my boost barely peaks past 1 Bar. I assumed I had a boost leak so after I noticed this I put back on the stock piping and while the RPM hang went away, my boost hasn't changed. Never payed attention to the boost before I put on the piping so not sure if it was always doing this. Any thoughts?
