If, this is the best you guys can come up with well....
Why not ask the guy to tune for 11.5 or whatever you feel is safe?
Since, there's nothing else that can go wrong, if you have good a/f's

Ok, really it isnt me just talking trash to talk trash. Advertising that he tunes turbo cars to that AF/r is basically screaming from the mountain top that he does not know what he is talking about.

I remember in the 90's, someone put together this really hot little Map for the b16. I knew the guy who got it done at the dyno, i was there.

A couple months later, he went to another shop around here, and they asked what was up with his car. They had a rom burner, and he sold them a copy of his rom for $25.

About a year later, suddenly everyone and their mom has a "Mugen stage III" rom tune, from this shop, and they got ripped off, and everyone got ripped off.

I am sure, that this guy just ganked some RS Enthalpy Maps or some JWT maps, any one who cannot accurately advertise themselves (dangerous af/r for turbo) is obviously cutting corners.

12.5/1 is good for N/A so he probably just copy/paste the text from another ad.

12.5/1 is a horrible AFR for NA, 14 AFR range is target for NA load tuning depending on octane.

12.5/1 is good if you want horrible gas milage and shitty response.

12.5/1 is excellent tune for race gas and turbocharged applications however.

Is it possible the tune was focused on maximum output for 100 octane?

Possibly tuned for 93 octane and +fuel pressure?

just throwing it out there.

Check out XAT also they are another excellent rom tune shop, although its just a band aid for a real quality EMS imo.

14/1 loaded n/a on pump is death dude, waaaaay too hot. Cruising yeah, but not WOT, not even nissan stock ecu's is running target 1 at wot.

check it again

13 is fine for wot.

15 is good for cruising if your looking for fuel economy.

If your trying to make power high 13s or low 14s on RACE GAS is ok.

Ive never seen a car overheat because it was running 13-14 afr under wot and na set up.

but I guess its possible depending on purity of octane.
