No tune required. Specs on americanmuscle.com says that the cai from bbk will give me +23hp and +32tq. Shaker is already on my car. It was already installed when I purchased the car. I've looked at different forums and I can't get a straight answer on how much extra HP the shaker is already giving me. I've read low as 2hp and as high as 20ph. I'm hoping that the HP will stack up if I do put in the CAI in.
