Launch control culprit
 

Hi guys,
Last week I posted about a funny noise on My 00Impreza Turbo engine. Well took the car in and the Tuner estimates it too be a small end bearing, the funny thing is that this noise started when I had the Unichip launch control fitted, last night a mate of mine phones me same car and model as me his engine doing the same thing, after inspection the launch control had caused his car's cambelt to jump a few teeth. Too say the least I am slightly pi$$d. the tuner has now caused damage to my motor. Any suggestions on recourse?
