Soooooo, I had a new stage 2 exedy clutch put in last week because my competition stage 3.5 clutch was slipping. Also replaced the timing belt. I was running 24 psi but now after the new add ons my psi dropped down to 10-12 psi. My car also makes a nasty rumble sound in my piping under the car when I rev it up to 5k. I'm fairly new to the evo scene. Can someone maybe point me in the direction as to what maybe wrong? Maybe I just need a tune but I'm really not sure. 😩

 

check to ensure that your intercooler piping did not get disconnected from a coupler somewhere
