DYNO RUN

But on the rest of the charts it seems to hold true... An A/F ratio of 10 is NOT agood thing

Oh, OK, I was wondering what I was missing with that. It was dead on 10.0, as if the computer were doing that intentionally..?

Do I understand it correctly in that you want 14.7 always?

No problemo, I'm the one that talks and types funny. Okay, if that is stock then take compared RK's dyno readings to mine. He has the "stock configuration" and I have the K&N Typhoon. He dyno'd 200WHP.

haha, and I think abstractly and quickly...bottlenecking it all into words is a chore! That is one reason why I am so wordy.

I would like to collect everyone's tables and graphs and crunch them for proper presentation; why go through all the time and expense and not have it all compiled?

Your stock dyno was bone-stock, silencers and filter, with Stage 1 correct?

Okay

Explain, why is it bad and is the 10 lean or rich?

Okay

Explain, why is it bad and is the 10 lean or rich in your opinion? The way that the chart reads is that the lower the number the richer the mixture and turbo have to run rich. Thats data that I have.

I think some folks have this backwards:
10.0 is rich, the higher the number, the leaner the A/F.

an AFR of 10 means 10:1 air:fuel, compare that to 14.7:1 air:fuel..

looking at those a/f ratios, i'd say there's room for more boost

I would be interested to see a followup dyno after the ECU relearns the lower intake resistance.
Will it drop the added 15 HP back down later, as 3 BAR says it will?

Kirby

I'm going to check in a month or so. The more I get into this the more I'm convinced that 3BaR and the PVO team know their stuff. We'll find if the ECU drops the HP down when I do another dyno run or if someone else does one. What I want would like to know is what ET should I be expecting to get from this setup?

You're right, you beat me to it.

What concerns me is that the dyno operators thought 10 was lean? maybe they were looking at the 14's in the 2000-2500 band, where the boost is on strong and the AF is still lean..

The 14's were what got their attention, especially with the first run entitled baseline lean. They were happy when it started to richen up.
