A couple days ago I bought some aftermarket intakes for my car, took the old air filters and plastic tubes of and installed my new intakes...well, I thought when I put those intakes on it would give me a little more speed, but I found out it is slowing me down. The reason is my buddy has a pretty quick car and I used to smoke him but now its opposite. Has anybody else had this problem when they installed intakes on their crossfires...someone I know said I needed to go get it tuned up since I changed intakes. If someone could help me It would be appreciated!!!
