Hondata just took delivery of their own Civic Si a few weeks ago, and they have finalized the initial release of their FlashPro support for Honda's newest compact sport sedan. As you can see in the below plots, gains are quite healthy and fully CARB-pending. They even have a calibration for flex fuel support ready to go. According to Hondata, the stock clutch starts slipping as torque is increased much more than 25-30% above stock levels, so if you're wanting to see much more than 270lb-ft from your 1.5T-powered Si, you're going to need to plan on a clutch upgrade at the minimum. To clarify, the stock engine is capable of delivering even more torque (and power) than is shown here, but the stock clutch cannot handle it.
