Hey guys, I put my stock intercooler on my car after having a Nisei one for some time now, I have had a tune with the Nisei intercooler. My question is this ever since I have had my stock one on when my car is cold "I first start her up", I have a problem when I hit full boost in a high gear it makes a huge popping sound lik a missfire. Do you think it has anything to do with the stock one being back on? Thanks

 

boost cut..
cheack the boost!!!

 

you think so? even though I still get full boost when it gets warm.
