That depends on which Powercard is being referenced. The one you're probably referring to is the oldest one and I don't think it's sold anymore.Look, if you actually did the slightest research, you would know that those mods you listed would have no performance gains from a Power-Card.
These aren't even adjustable piggy back ecu's, they're just band-aids for F/I. Bottom line, you don't need this right now.
