You've adjusted the Bowden cable to shift quickly. I have mine out as far as I want it and have to lift the accelerator to shift into fourth before 55 mph when being aggressive.
The further out it is, the longer it'll stay in each gear when under heavy acceleration.
Here is the SD, listen closely at second number 2 (chirp). No resonators, just a straight pipe back to an ANSA muffler.
