Hi,

Just as a tip:

13.8 at WOT sounds a little lean for a turbo car for thermal (not power) reasons. The closer you get to stoich (14.7) the higher the cyl. head and piston crown temps. Therefore also more knock probability. CHTs have a peak at around stoich.
For a street driven car at partial load and idle go for stoich (14.7) for smog reasons. On a race-car at partial load I would go for ~15-16 if possible (avoid lean surge). That makes it run at best BSFC and therefore can lengthen the time between refueling stops.

Regards,
Klaus
