2006-2011 Civic Si/CSX-S – Ultimate Tune

Original price was: $349.00.Current price is: $279.00.

Whether its the FG2 or family oriented FA5… #JediVoice“This is the 8thgen tune you are looking for.” Its true! This tune includes a complete Wide Open Throttle (WOT) analysis and tune as well as a complete part throttle and knock analysis package. The WOT portion is similar to what is done at a dyno shop except with more revisions while the part throttle tuning is focused on zeroing Short Term Fuel Trims (STFT) which will not only improve WOT transitions but also inturn improve throttle responseperformance, low end torque and fuel mileage. A minimum of 6 revisions, although there is no charge if 7 or more are needed to make things perfect as long as the modifications to the car have not changed.
