Oh my! This injection is awesome.

Throttle response is instant and wicked. Be careful doing the burn out. I hit the rev limiter once when I hit it too hard.

The bottom line:

1.25 sixty foot
5.76 at 118 mph at the 1/8 mile mark,
9.12 at 145 mph at the 1/4 mile finish line.

The air was mineshaft, about -600 to -1000 ft density altitude, but with the sunshine the track was hooking. In fact I need to do more work to calm the wheel stand. It tripped the sixty foot timers with the rear tires everytime I smacked the launch (footbrake). The 1.25 was a quick roll-on of the throttle. I did some things to try and stop it, but I need to do more.
