How does my dyno look?

I was wondering what people though if this tune. I spoke to the tuner about my AFR. I felt it was a bit lean but he said it's right were it needs to be.

I'm not a tuner, but that would be lean even on E85. You want to be between 10.8 to 11.2 for pump gas. Is this at 27 psi?

27psi 93oct.

I'd say that's lean. We always aim for 11.7 on my cars. On my sr20 that made 460whp it was 11.5 on 93 octane with 28psi of boost. If we went any leaner it'd start detonating.

Remember you can run leaner with less timing. All depends on the full setup and what the car likes. It looks like it's running mid to high 11s. I usually shoot for 11.4.

Looks like it's under 12 which is a good thing. What exactly does your AFR gauge show at WOT?
|
my car is always .3 to .5 richer on the street than the dyno, what does your gauge read?
|
My gauge seems to stay around 11.4 but the graph shows 11.7. Just wonder if my gauge is off. I'll have to run evescan to see if there's ever any knock.

Seems fine. 11.4, 11.7 are both safe numbers.

Thanks for all your responses. {thumbup}

Looks like great result.
What did you end up getting for a CBE? Kevin |
