Is this Air:Fuel ratio right??
So got a tune today and the tuners said the Air Flow Meter was dodgy, so they put a new one in because the car was running lean, but looking at the dyno sheet I'm not sure. Any comments.
The red line was before tune, blue is after tune.

Should have stuck with the first tune. 14.0:1 is fine for N/A thats not running big hp.
But jesus the new tune is running about 11.7:1 at one place on that readout. Thats way too rich for N/A, your just wasting fuel.
As the old saying goes, Lean is mean lol.

looks not bad to me stock looking fuel curve.i normally tune rich till max torque then lean it out to 13ish to make power
I tune the oldschool way fear on the passengers face and knuckle colour cant go wrong

So do people think I should take it back and ask them to change that?
If it makes any difference, it has a mild cam and compression around the 10.5:1 mark, always 98 octane.

Give me a sec I'll post it up.
But torque curve (from what I can tell) is nice and flat in a large range.

I've blacked out the company name because I don't want to seem like I'm bagging any company, not my intent here.
Well I suppose a bit rich is better than a bit lean, especially with raised compression.
