Chip - what afrs do you aim for at diff boost levels etc?
Depends on the exhaust manifold etc.
There isnt one AFR that fits everything.
If in doubt though, RICH!
IME going from low 12s to high 10s takes only a few percent off the power output, and yet makes everything MUCH safer, so Im a big fan of the extra safety in exchange for a minimal drop in power.
Depends what you are doing though, if its remaps for a standard car, you need to do what your competitors do to match their figures, so I understand why must chips run leaner than I would with my ultra conservative approach.
Until the turbo is maxed, generally I would sooner make more power with a little more boost than with going leaner, and once it is maxed, I would sooner fit a turbo that isnt.
