Well if you can change the oil, you can also replace your blipper with the translogic and still be in the green.
Time is money too.
Mine works flawlessly. Crisp and quick shifts up/down without fail. Combined with CNC Racing Rearsets. Eye-to-eye shift linkage length and gear selector position adjustment is very important here: a few mm can have a big impact.
OEM or aftermarket rearsets on your 1299?
Don't take it the wrong way, but are you sure you're using it in the right way?
Are you heavy on the throttle when you down shift?
And no throttle when you're upshifting?
I get mixed results at the track, but only because my technique sucks.
