Sorry to jack the thread but I though that this would be a good time to do it...heh.

The ECU reprograms done by either of the companies... do they install new software or somehow alter the existing software on the ecu?

I am asking this because I am wondering if an accidental ecu flash done by keeping your foot on the pedal while the car is on would upset the performance increase?

Also does the ECU reprogram do anything about the red line problems?
