Dyno run sheet

[Aurora40]

I'm no expert, but I've heard tailpipe widebands read lean by about half a point or so? So it might not be quite as bad as the 13.9-14:1 seems to indicate.

Also, wouldn't you lose a little power richening it up (though gain a huge margin of safety)? All I mean is a non-crap tune might not improve the power, though it certainly looks like it would be a good idea.

So do you have headers or what?

I think his car being that lean would cost power. it looks way lean , it would be fun to see what happens when they add fuel .if i had to guess 410to the wheels .but i am no expert

A40,

The best place for a WB is in the collector next to the NB sensor. I think next time I go to the dyno, I'll have my ZT-2 hooked up. Be an interesting comparison between the tailpipe and the collector. My first run on thedyno showed a 13.4:1 AFR. Dropping that to 12.8 did nothing for power either way but a bit more peace of mind in case of bad gas for example.
