But yes, I experienced first-hand what timing flatline does to a car (ran my friend's C63 with an OE tune, we are close to even until I shift into 5th and he proceeds to put 3 car lengths on me from say 125-155). I also ran laloosh aka Clap135 at the drag strip, dead even until I shift into 4th, then he puts 2 cars on me.
But sure, no one ever cared, sigh. Imagine how I felt after dealing with this for over two years.
Rumor has it that they are working on it. Hopefully it will be fixed soon.
