Default What a dyno screen shot should NOT look like

This is a "certain" members truck (not mine) with a STS and stock fuel system trying to run 10 lbs of boost. Notice the injector duty cycle and the actual A/F (top) verses the commanded A/F (bottom). Luckily he was still able to drive home (100 miles) even after making a second run that was even uglier

Calculated inj duty cycles would be somewhat lower if commanded AFR was something like 11.0 :1 but would still be way over 100%. Looks like he was out of injector before 4000 RPM at a commanded AFR around 10.0:1. Could probably set the rev limiter to 4500 RPM with a commanded AFR of say 11.0:1 with no safety factor. But what fun would that be!

Ouch. Thats a big KR spike.

I think your friend should not leave the house -- he's used up all his luck for this year

You should see the KR on his second run Can you say 8*...?

All most needed a bucket to take the pieces home
The dyno guy did tell him they had a mop and a bucket he could use to clean up the mess if he wanted to go again
