^ Its not gonna happen on their "Stage 1" kit. Maybe with the stage 3 they won't lose the lbs...if thats what you're referring to. It's been shown a few times already that the small compressor housing cannot flow enough to sate a free flowing exhaust. I guess in other words it's not well suited for a car with LTH's or the like, but rather a car that is supposed to pass CARB. If I had to pick up a GTM SC and not care about CARB, I would not be at all interested in stage 1. Maybe stage 2. Definitely stage 3. Obviously stage 3 would flow more...but then you'd lose the insta-spool and low end torque qualities that people like about this kit. A while back I looked at the flow charts of the rotrex units used in the different GTM kits....the Stage 3 unit flows similar to the vortech unit in the Stillen kit. I'm not sure why anyone planning to run headers and exhaust is considering the GTM stage 1. That's my take on things. Not starting a fire here, but I would like know what other folks think about that.
