Car getting tuned

[BlitZ]

Hi All,

Can i please get some confirmation of a few things..

I am gonna to ask for 12.8 - 13.0 A/F ratio... would that be safe all year around, seeing track days etc etc, if tuned on a moderatly cool day?

I suppose tunning is done close loop off.. then back on when complete?

Is road tune primarily to tune for part throttle or for bottom end or for some other reason (people who normally cant explain it to me just say its for driveability)?

and last but not least.. does a stock b series (b18c2/18c6/16a,16b) motors run lean, rich or crap at the very top end like at 8k+? what fuel mixture ratio is expected at WOT?


thanks in advance,
dan
