I'm replying to this topic, as the subject was exactly what my issue is about.So, I was on rolling road today with my VTS Xsara. Two runs were pulled. The thinner, cutted line (better power and torque) was the run with original ECU and the solid, thicker lines are with unsuccessfully modified ECU. Best power was 172hp and max torque was 213Nm (=158 ft/l  . The engine is 50k ago rebuild. The only tuning is custom made race exhaust without cat.Do you guys have any explanations for behavior of the torque curve, after 6000rpm? The guy that was running our car, told that 45* degree straight line tells probably about some restriction. Or are the original cams just on their limit? What about stock injectors?  ________________________________________ www.facebook.com/VTSracingteam |
