From my understanding it only "splits" power to the wheels when there's a need for speed differences and load variance. I don't see how the 4:1 would help in drag racing. I'm not sure why, but on a launch I'm chirping the front tires. Is that bad?

I swapped out my K03 for a K03s about 1/2hr before I drove down to the track. Maybe it was me, but from driving before and after it didn't feel like it dropped off as hard. The stock K03 I could actually feel it fall off @5500, now it feels like a SOHC running out of wind past 6K.
Part of the reason I swapped it over was b/c I had an exhaust leak between the manifold and the turbo. I had the K03s and 1 of the turbo to manifold bolts was too long and didn't fasten the turbo to the manifold uniformly. It was like that when I bought it, I just fixed it now... 7 months later.
I found that at the end of 2nd gear, if I shift at 6500 I come into 3rd right at 4500rpm. It seems to pull 3rd harder that way. I didn't like hitting 4th for the last 150ft or so either. I'm happy with what I got. I was expecting 15.2's
