06 cts-v dyno run... updated with results
#22
Thanks for the responses. Guy said he would like to see the top end in the 12's if I was spending a lot of time running through the long upper gears. Which I don't. I probably won't have any more tuning done to the engine as of now. Just gotta get some premo in there

I never charge for retunes.
The air fuel ratio is off a bit, and needs to be addressed. If you send it over I can make it exact for you based on that dyno graph.
My guess though is that you have a dirty mass air meter. If you cleaned it before you did a run it would have probably fixed the air fuel ratio. But I can do it in software as well..
And its definatly not a good thing to be running a 93 oct performance tune on 89...

Glowing headers? Glowing how much? That doesn't necessarily mean lean. In fact, you know what would indicate lean or rich? The actual AFR number as measured by a wideband. 13.5:1 is a little high, but not crazy. Ideally, you'd ensure there are no air metering issues and then get the tune looked at if the problem doesn't go away.

Even with all of the real facts removed, REALLY?
No worries, I will let you try again. I'll be right here waiting.

I agree I wouldn't base much on a 21k rpm F1 engine, but two long 4th gear pulls two minutes apart I wasn't real surprised to see my headers glow for a few seconds at the end of the second run. I'm going to clean my MAF and when the weather warms up I'll get back in touch with Jesse about seeing if he can add a bit more fuel at WOT high rpm's to get into the high 12s.
Like I said I posted all the info I had in order to learn what was normal or not, and if no body else's headers ever glow I know I need to get it tweeked for a bit more fuel. Thanks again.
