The Acura TSX (c. 2004) was originally developed to produce 200hp and 160ft/lbs of torque. In 2006, the ECU was slightly modified to produce 205hp and 164ft/lbs of torque. The number seem insignificant at a glance; however, 0-60 dropped from 8.1sec (SportCompactMagazine.com) to 7sec(Edmunds.com).
If you have a 2009 model (the revamped body style) the engine is mostly the same except that horsepower is slightly decreased while torque is slightly increased. Once again this is largely due to ECU modification.
