Do you tune for a living DANGERMAN4??
we are not talking martins tunes alone here, it just happens to be one of his... many top level tuners delve far leaner than 12 and 12.5. look at le mans cars etc
i also plainly said on cusomers cars they will get the plain jane tune, mates though always get the more agressive tunes as thier cars are well know by me therefore i am more able to exploit them safely..... never ever lost or hurt an engine.
