a rich afr is better than a poor blown motor
*Don't look just at the AFR , timing is very important when it comes to tuning, you can have detonation even at low 10 AFR if the timing is not right. The zetec engine(stock) does not like too much timing when boosting on pump gas. Also a good tuner should look at the overall picture;like MAF voltage,fuel pressure,IAT,knock sensor,EGT and so on...
