I have been tuning my vacuum system to resolve a hard shift, early shift and flaring. I have removed the lines to EGR, tuned my VCV and adjusted my bowden cable so it is shifting as good as I am going to get it. The only thing I have lost now is when I am in 4th gear, or any gear for that matter, when the RPMS are still low (2000) and I floor the pedal it used to bring me into a super drive or whatever you would call this. It would really give me some power and race the rpms when I needed it. I am not sure what you call this. But now, when I floor the pedal, it just slowly goes faster, no more flash of power. sorry for lack of correct terminology. I suspect the bowden cable adjustment may have caused it. It is nice to know you can kick it up a gear when you need the power, how do I get that back? And what it is called? Feels like superdrive or something to that effect. There must be a name for this.
