Or you could put your foot down 25% @ 0 psi and 50% @ 5 psi.

I think that's what most people don't realize is that when you modify these trucks you need to learn how to redrive them. You've gotta learn how to shift with the RPM's higher, use less throttle to acheive the same acceleration, keeping boost up. It's just a trade off you have to make when you modify these trucks. I had to relearn how to drive my truck after installing the KSB-1. Yes it spools fast but not near as fast as my stock HY so I had to learn how to give it less throttle and still acheive the same acceleration while reducing smoke output. I had to do the same thing with the smarty when I first put it on there.

But like Mike said, that's not conducive to drag racing...

I was more referring to Dieselcamper wanting less low smoke down low.

More testing today. Previous results on my personal dragway was 85 mph with sw3, 88 mph with sw7, and now 90 mph with sw9. My truck launches harder on the higher sw's.
