Hello Saab driver, I have had a Saab for some time now. Not that the engine would be too small, but such a proper HirschTuning for a birthday would not be bad. But I have not had the opportunity to inform about it lately (for the purpose of building a house). So my questions to the tuning experts among you: Can you install this control unit T7 yourself? Changes in the insurance classification of the vehicle? Has anyone ever done this with a 2.0 LPT with 150hp? We nn yes what was the result? (consumption, starting weakness, rideability…) If anyone else is interested, I have a 9-3, built 2001, 150hp, but am currently very satisfied with the feed constant of the Saab. BG Andreas PS: Have been reading the forum for some time and find it great
