Lean condition
I'm working on a 2003 4.6L Mustang with a vortech charger. After the tune it ran perfect. It cam back with a melted plug, no other damage to the engine thankfuly. I installed a wideband 02, and the afr is 14.7:1 at idle, and goes as high as 17 on the meter, plus I hear detonation. fuel presure is at 40 psi. any ideas,
Thanks in advance for any help.

Did you upgrade injectors? You may be at the limit of their capacity, at given psi.
I do know that the same injectors will deliver more if you can raise fuel pressure, but you will need to revisit your tune.
