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.

Why do you still run a cobb tune if it doesnt perform so great? Or why havent you stacked a jb4 on?

Thats like having a jb4 g4 and saying you dont need to update cause it runs fine even though your throwing codes lol
