OK, So had CObb installed for the past 4 months or so. Been running S1 Agrressive map from day 1. No issues. I was gone for 2 weeks and when I got back drove the car and I say 10min into the drive and as I was hard accelerating from a stop sign, I felt the accelaration was relatiely normal but I think (can prove that) the car went past redline - - it just felt odd at the end of the accelaration band (Pre upshift). Needless to say, i notice the engine sign pop and says malfunction reduce power. Car still drove fine...I panicked. But I continued driving home with no hard accelaration. I parked..An hour later I drive again and malnfunction is no longer showing and car continues to drive fine since. Any ideas people??
