So after living with the TTS280 for a full summer season and 6K miles I'd say it's perfect for my daily driver (summer only) but nothing is always perfect. For highway driving and canyon carving it is perfect. It spools up about 500 rpm later that a hybrid, so my personal opinion is that it wouldn't be my first choice for auto cross. For that I'd go with the Whoosh Hybrid. But as a daily driver I'm not spinning tires at every red light and stop sign without trying anymore. I can actually start moving without wheel spin and the power pulls all the way to 7K rpm and it pulls hard. It probably isn't the best turbo for all out power on a fully modified FiST, but it works great as a daily driver and it's a huge improvement over stock! Good value and good performance.....exactly what I was looking for!
