Not too many SuperFlow dyno maps on here. Anyone know the deltas between different dynos vs Dynojet?

That's like what... a 60whp gain over what a stock B25 dyno? Practically looks like a B30 crank was swapped in between the runs

You're running a bit lean though, you could probably pick up a few more ponies by bringing that A/F ratio down, otherwise it looks good. I'd kill to have that much power. Then again who buys a 2.5 for power, right...

Really? I thought I was running rich?

I get awful gas mileage, my car backfires, and my exhaust tips are filled with soot.

How do I adjust my AFR?

14.7:1 is the ideal air:fuel ratio for (effectively) lower emissions, however NA cars tend to make the best power between 12.5-13.5:1, depending on the engine.

The lower the first number, the less air you get for a given amount of fuel, so more rich. 10:1 would be rich, 20:1 would be lean.

Southpaw, on you're dyno graph - on the AFR chart, that red dotted/slashed line is a general idea of where you want to be. You're running a little lean, but good for emmissions and therefore you're cats (if you still have them).

The most common way to correct the AFR's is to get an aftermarket tune.

I have an AA track pipe which deletes the cats.

Oh yea? That's different from an ECU chip, right? I have an AA stage 5 chip.

Your AFR's are fine. If you want perfect ones for racing or something then you'll need alot more than just an "off the shelf" ecu chip/tune.
