If you want more power then a stock setup will provide, spend money on an IC, IC piping and HFC (about $1200), then get a custom tune. If I would have had the IC and HFC, I could have been dyno tuned to upwards of 320hp at the wheels. Instead I had to settle for 286hp. I have heard good and bad things about Trifecta, more bad lately as they've moved on to the next gen 2.0L from the ATS, Camaro, CTS and Buick Regal. Dave at DDM is awesome!!!! He's almost ALWAYS available to help.
